Recombinant Murine LIX/CXCL5 (93a.a.) (rMuLIX/CXCL5)
Catalogue Numbers: PR2027-5, PR2027-20
Sizes: 5µg, 20µg
Source: Escherichia coli
Molecular Weight: 9.8 kDa, a single, non-glycosylated polypeptide chain containing 93 amino acids.
Purity: >97% by SDS-PAGE and HPLC analyses.
Biological Activity: Fully biologically active when compared to standard. Determined by its ability to chemoattract human peripheral blood neutrophils using a concentration range of 10.0-100.0 ng/ml, corresponding to a Specific Activity of ＞1 x 104 IU/mg.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation: Lyophilized from a 0.2mm filtered concentrated solution in 20mM PB, pH 7.4, 150mM NaCl.
AA Sequence: APSSVIAATE LRCVCLt VTP KINPKLIANL EVIPAGPQCP t VEVIAKLKN
QKEVCLDPEA PVIKKIIIQK ILGSDKKKAK RNALAVERTA SVQ
Endotoxin: Less than 1EU/mg of rMuLIX/CXCL5 as determined by LAL method.
Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
Storage: This lyophilized preparation is stable for several weeks at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
Usage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China
Description: The murine homolog of ENA-78 is called LIX. ENA-78/LIX is a CXC chemokine that signals through the CXCR2 receptor. It is expressed in monocytes, platelets, endothelial cells, and mast cells. ENA-78/LIX is a chemoattractant for neutrophils. The three naturally occurring variants of human ENA-78; ENA 5-78, ENA 9-78 and ENA 10-78, contain 74, 70, and 69 amino acid residues, respectively, and possess the same biological activity. ENA-78/LIX contains the four conserved cysteine residues present in CXC chemokines, and also contains the 'ELR' motif common to CXC chemokine that bind to the CXCR1 and CXCR2 receptors.
