Human EGF was isolated from urine based on its inhibitory effect on gastric secretion and named urogastrone, accordingly. EGF is prototypic of a family of growth factors that are derived from membrane-anchored precursors. All members of this family are characterized by the presence of at least one EGF structural unit (defined by the presence of a conserved 6 cysteine motif that forms three disulfide bonds) in their extracellular domain. EGF is initially synthesized as a 130 kDa precursor transmembrane protein containing 9 EGF units. The mature soluble EGF sequence corresponds to the EGF unit located proximal to the transmembrane domain. The membrane EGF precursor is capable of binding to the EGF receptor and was reported to be biologically active.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"100µg","offer_id":42880312279219,"sku":"PR1019-100","price":185.88,"currency_code":"USD","in_stock":true},{"title":"500µg","offer_id":42880312311987,"sku":"PR1019-500","price":350.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51.jpg?v=1701973209"},{"product_id":"recombinant-murine-epidermal-growth-factor-rmuegf-pr2014","title":"Recombinant Murine Epidermal Growth Factor (rMuEGF ) - PR2014","description":"\u003cp\u003eRecombinant Murine Epidermal Growth Factor (rMuEGF)\u003c\/p\u003e\n\u003cp\u003eCatalogue Numbers: PR2014-100, PR2014-500, PR2014-1000\u003c\/p\u003e\n\u003cp\u003eSizes: 100µg, 500µg, 1.0mg \u003cspan data-mce-fragment=\"1\"\u003e(contact us for the 1.0mg option)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSource: Escherichia coli\u003c\/p\u003e\n\u003cp\u003eMolecular Weight: 6.0 kDa, a single non-glycosylated polypeptide chain containing 53 amino acids, including 3 intramolecular disulfide-bonds.\u003c\/p\u003e\n\u003cp\u003ePurity: 97% by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\n\u003cp\u003eBiological Activity: Fully biologically active when compared to standard.

FGF acidic and basic, unlike the other members of the family, lack signal peptides and are apparently secreted by mechanisms other than the classical protein secretion pathway. FGF acidic has been detected in large amounts in the brain. Other cells known to express FGF acidic include hepatocytes, vascular smooth muscle cells, CNS neurons, skeletal muscle cells, fibroblasts, keratinocytes, endothelial cells, intestinal columnar epithelium cells and pituitary basophils and acidophils. As with other FGF’s, FGF acidic exhibits considerable species crossreactivity. FGF acidic and FGF basic stimulate the proliferation of all cells of mesodermal origin, and many cells of neuroectodermal, ectodermal and endodermal origin.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10µg","offer_id":42880312967347,"sku":"PR1030-10","price":185.88,"currency_code":"USD","in_stock":true},{"title":"50µg","offer_id":42880313000115,"sku":"PR1030-50","price":350.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_c97d3bf8-82c0-4d36-8b68-c35ffde5f952.jpg?v=1701973218"},{"product_id":"recombinant-human-interleukin-2-rhuil-2-pr1065","title":"Recombinant Human Interleukin-2 (rHuIL-2) - PR1065","description":"\u003cp\u003eRecombinant Human Interleukin-2 (rHuIL-2)\u003c\/p\u003e\n\u003cp\u003eCatalogue Numbers: PR1065-10, PR1065-50, PR1065-1000\u003c\/p\u003e\n\u003cp\u003eSizes: 10µg, 50µg, 1.0mg \u003cspan data-mce-fragment=\"1\"\u003e(contact us for the 1.0mg option)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSource: Escherichia coli\u003c\/p\u003e\n\u003cp\u003eMolecular Weight: Approximately 15 kDa, a single non-glycosylated polypeptide chain containing 134 amino acids.\u003c\/p\u003e\n\u003cp\u003ePurity: \u0026gt;97% by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\n\u003cp\u003eBiological Activity: Fully biologically active when compared to standard.

The four vertebrate syndecans have two conserved cytoplasmic domains and divergent extracellular portions, except for HS attachment sites. Syndecan4 is the most similar to Syndecan2, but is more universally expressed and is found in virtually every cell type. Expression can be upregulated by TGFβ2 and in response to mechanical stress in smooth muscle, wound healing, arterial injury or acute myocardial infarction, probably in response to at least one inflammatory mediator. Human Syndecan4 ECD shares approximately 79%, 78% and 81% aa identity with mouse, rat and porcine Syndecan4 ECD, respectively. Addition of  20 80 disaccharides per side chain adds considerably to the size of the 20 kDa core protein. Noncovalent homodimerization of Syndecan4 is dependent on the transmembrane domain. The HS chains can bind fibronectin, SDF1, antithrombin, FGF2, midkine and tissue factor pathway inhibitor and can present FGF2 to its receptors. Proteolytic cleavage by plasmin, thrombin or a metalloproteinase may create a functional ectodomain. Genetic disruption of the Syndecan4 gene causes a mild phenotype, presumably due to compensation by other syndecans, but mice have an increase in placental thrombi as well as defects in wound healing and response to endotoxin shock.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10µg","offer_id":42880589660339,"sku":"PR1117-10","price":185.88,"currency_code":"USD","in_stock":true},{"title":"50µg","offer_id":42880589693107,"sku":"PR1117-50","price":350.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_eb95ed5d-c5b0-49db-a5d5-b735115b038b.jpg?v=1701981992"},{"product_id":"recombinant-human-tumor-necrosis-factor-alpha-rhutnf-α-pr1125","title":"Recombinant Human Tumor Necrosis Factor-alpha (rHuTNF-α) - PR1125","description":"\u003cp\u003eRecombinant Human Tumor Necrosis Factor-alpha (rHuTNF-α)\u003c\/p\u003e\n\n\u003cp\u003eCatalogue Numbers: PR1125-10, PR1125-50, PR1125-1000\u003c\/p\u003e\n\n\u003cp\u003eSizes: 10µg, 50µg, 1.0mg (Contact us for the 1.0mg option)\u003c\/p\u003e\n\n\u003cp\u003eSource: Escherichia coli\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight:Approximately 17.5 kDa.

TNF-α occurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. The naturally-occurring form of TNF-α is glycosylated, but non-glycosylated recombinant TNF-α has comparable biological activity. The biologically active native form of TNF-α is reportedly a trimer. Human and murine TNF-α show approximately 79% homology at the amino acid level and crossreactivity between the two species. Two types of receptors for TNF-α have been described and virtually all cell types studied show the presence of one or both of these receptor types.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10µg","offer_id":42880589889715,"sku":"PR1126-10","price":185.88,"currency_code":"USD","in_stock":true},{"title":"50µg","offer_id":42880589922483,"sku":"PR1126-50","price":350.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_b086ee07-f8f4-4d53-b239-1c5e06e4db43.jpg?v=1701981995"},{"product_id":"recombinant-murine-fibroblast-growth-factor-basic-rmubfgf-pr2015","title":"Recombinant Murine Fibroblast Growth Factor-basic (rMubFGF) - PR2015","description":"\u003cp\u003eRecombinant Murine Fibroblast Growth Factor-basic (rMubFGF)\u003c\/p\u003e\n\n\u003cp\u003eCatalogue Numbers: PR2015-10, PR2015-50, PR2015-1000\u003c\/p\u003e\n\n\u003cp\u003eSizes: 10µg, 50µg, 1.0mg (Contact us for the 1.0mg option)\u003c\/p\u003e\n\n\u003cp\u003eSource: Escherichia coli\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight:Approximately 16.2 kDa, a single non-glycosylated polypeptide chain containing 146 amino acids.\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt;98% by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\n\n\u003cp\u003eBiological Activity: Fully biologically active when compared to standard.

The IGFs are similar by structure and function to insulin, but have a much higher growth-promoting activity than insulin. IGF-II expression is influenced by placenta lactogen, while IGF-I expression is regulated by growth hormone. Both IGF-I and IGF-II signal through the tyrosine kinase type I receptor (IGF-IR), but, IGF-II can also signal through the IGF-II\/Mannose-6-phosphate receptor.

Endogenous IL-1ra is produced in numerous animal disease models as well as in human autoimmune and chronic inflammatory diseases. It binds to IL-1 receptors in competition with IL-1, but does not elicit intracellular response from this binding. Its role in counteracting the proinflammatory effects of IL-1 is being studied by numerous research groups. IL-4 and IL-13 have been shown to amplify the stimulatory effect of IL1-beta on the production of soluble and intracellular forms of IL1-ra.The regulated expression of IL1ra in various cell types has been shown to be influenced by cytokines. In synovial fibroblasts the synthesis of IL-1ra is markedly enhanced by IL-1 , TNF-alpha , or PDGF.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"20µg","offer_id":42880591691955,"sku":"PR1051-20","price":185.88,"currency_code":"USD","in_stock":true},{"title":"100µg","offer_id":42880591724723,"sku":"PR1051-100","price":350.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_f29b585e-98d9-4b67-9317-765220b4e5c9.jpg?v=1701982012"},{"product_id":"recombinant-human-kallikrein-1-rhuklk-1-pr1077","title":"Recombinant Human Kallikrein-1 (rHuKLK-1) - PR1077","description":"\u003cp\u003eRecombinant Human Kallikrein-1 (rHuKLK-1)\u003c\/p\u003e\n\n\u003cp\u003eCatalogue Numbers: PR1077-20, PR1077-100, PR1077-1000\u003c\/p\u003e\n\n\u003cp\u003eSizes: 20µg, 100µg, 1.0mg (Contact us for the 1.0mg option)\u003c\/p\u003e\n\n\u003cp\u003eSource: Escherichia coli\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight:Approximately 29.7 kDa, a single non-glycosylated polypeptide chain containing 262 amino acids with 6×His at C-terminus.\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt;90% by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\n\n\u003cp\u003eBiological Activity: Measured by its ability to cleave a flourogenic peptide substrate Pro-Phe-Arg-7-amido-4-methylcoumarin (PFRAMC).\u003cbr\u003e\nThe specific activity is \u0026gt; 2,000pmoles\/min\/μg.\u003c\/p\u003e\n\n\n\u003cp\u003ePhysical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.\u003c\/p\u003e\n\n\u003cp\u003eAA Sequence: MWFLVLCLAL SLGGTGAAPP IQSRIVGGWE CEQHSQPWQA ALYHFSTFQC GGILVHRQWV LTAAHCISDN YQLWLGRHNL FDDENTAQFV HVSESFPHPG FNMSLLENHT RQADEDYSHD LMLLRLTEPA DTITDAVKVV ELPTEEPEVG \u003cbr\u003e\nSTCLASGWGS IEPENFSFPD DLQCVDLKIL PNDECKKAHV QKVTDFMLCV \u003cbr\u003e\nGHLEGGKDTC VGDSGGPLMC DGVLQGVTSW GYVPCGTPNK PSVAVRVLSY  VKWIEDTIAE NSHHHHHH\u003c\/p\u003e\n\n\n\u003cp\u003eEndotoxin: Less than 1EU\/mg of rHuKLK-1 as determined by LAL method.\u003c\/p\u003e\n\n\u003cp\u003eReconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom.

The protein also exerts antiproliferative, immunoregulatory and proinflammatory activities and is thus important in host defense mechanisms. IFN-γ induces the production of cytokines, upregulates the expression of class I and II MHC antigens, Fc receptor and leukocyte adhesion molecules.

Flt-3 was first discovered as a member of the class III subfamily of receptor tyrosine kinases (RTK) whose expression among hematopoietic cells was found to be restricted to highly enriched stem\/progenitor cell populations. Additional class III RTKs include the receptors from SCF, M-CSF and PDGF. Not surprisingly, Flt-3 ligand is also structurally related to M-CSF and SCF. All three cytokines have been shown to exist both as type I transmembrane proteins and as soluble proteins. The predominant human FL isoform is a transmembrane protein that can undergo proteolytic cleavage to generate a soluble form of the protein. An alternatively-spliced FL mRNA, encoding a soluble form of the human FL, has also been identified. FL is widely expressed in various human and mouse tissues. At the amino acid sequence level, human and mouse FL are approximately 72% identical and the two proteins exhibit cross-species activity. FL has been shown to synergize with a wide variety of hematopoietic cytokines to stimulate the growth and differentiation of early hematopoietic progenitors.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"2µg","offer_id":42880592445619,"sku":"PR1031-2","price":185.88,"currency_code":"USD","in_stock":true},{"title":"10µg","offer_id":42880592478387,"sku":"PR1031-10","price":350.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_c83cecc2-c04d-477e-b827-3de68260779c.jpg?v=1701982023"},{"product_id":"recombinant-human-glia-maturation-factor-beta-rhugmf-β-pr1033","title":"Recombinant Human Glia Maturation Factor beta (rHuGMF-β) - PR1033","description":"\u003cp\u003eRecombinant Human Glia Maturation Factor beta (rHuGMF-β)\u003c\/p\u003e\n\n\u003cp\u003eCatalogue Numbers: PR1033-2, PR1033-10, PR1033-1000\u003c\/p\u003e\n\n\u003cp\u003eSizes: 2µg, 10µg, 1.0mg (Contact us for the 1.0mg option)\u003c\/p\u003e\n\n\u003cp\u003eSource: Escherichia coli\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight:Approximately 16.5 KDa, a single non-glycosylated polypeptide chain containing 141 amino acids.\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt;98% by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\n\n\u003cp\u003eBiological Activity: Data Not Available.\u003c\/p\u003e\n\n\u003cp\u003ePhysical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.2m filtered concentrated solution in 20mM PB, pH 7.4, 130mM NaCl.\u003c\/p\u003e\n\n\u003cp\u003eAA Sequence: SESLVVCDVAEDLVEKLRKFRFRKETNNAAIIMKIDKDKRLVVLDEELEGISPDELKDELPERQPRFIVYSYKYQHDDGRVSYPLCFIFSSPVGCKPEQQMMYAGSKNKLVQT AELTKVFEIRNT\u003cbr\u003e\nEDLTEEWLREKLGFFH\u003c\/p\u003e\n\n\n\u003cp\u003eEndotoxin: Less than 1EU\/g of rHuGMF-b as determined by LAL method.\u003c\/p\u003e\n\n\u003cp\u003eReconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom.

Streptavidin can bind to four moles of biotin per mole of protein,and it shows extremely high affinity, approximately 10,000-15,000 Da. Streptavidin lacks the carbohydrate side chains present on avidin and has an isoelectric point of 6.5 to avidin's 10 far closer to that at which most useful biological interactions occur. As a result, Streptavidin frequently exhibits much lower non-specific binding than avidin does.","brand":"BioWorld","offers":[{"title":"5mg","offer_id":42882246803635,"sku":"BK0163-5mg","price":823.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_0c63002f-a90e-4425-be5f-d3ddd3560864.jpg?v=1702050007"},{"product_id":"recombinant-tev-protease-his-bk0165","title":"Recombinant TEV Protease, His - BK0165","description":"\u003cp\u003eRecombinant TEV Protease, His\u003c\/p\u003e\n\n\u003cp\u003eCatalogue Numbers: BK0165-1000, BK0168-10\u003c\/p\u003e\n\n\u003cp\u003eSizes: 1000IU, 10μg\u003c\/p\u003e\n\n\u003cp\u003eSource: Escherichia coli\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: 28.4 kDa, observed by reducing SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt; 95% by SDS-PAGE analyses.\u003c\/p\u003e\n\n\u003cp\u003eBiological Activity: 6 IU\/μl.

The protease is used to cleave affinity tags from fusion proteins. The optimal temperature for cleavage is 30°C; also it can be used at temperature as low as 4°C. It is recommended that the cleavage for each fusion protein be optimized by varying the amount of recombinant viral TEV protease, reaction time, or incubation temperature. It can be removed by Ni2+ affinity resin.Recombinant Tobacco Etch Virus Protease (rTEV) contains 231 amino acids with N-terminal His tagged.

It is produced by keratinocytes, dendritic cells, hepatocytes, neurons and epithelial cells. IL-7 binds and signals through IL-7 receptor, a heterodimer consisting of IL-7 receptor alpha and common gamma chain receptor. IL-7 plays a role in regulating early B cell and T cell development. It is also important for optimal dendritic cell-T cell interaction.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"25μg","offer_id":42882257223859,"sku":"BK0255-25","price":494.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_f50d6af4-1f4a-4b82-b805-4ac9420fdd76.jpg?v=1702050167"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/collections\/LOGO_Clipped_for_website_51ccf852-f6e4-47ed-8898-8e3cba561117.png?v=1763065514","url":"https:\/\/afsbio.com\/collections\/bioworld.oembed?page=6","provider":"AFSBio Inc.","version":"1.0","type":"link"}
