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.\u003c\/p\u003e\n\n\u003cp\u003eUsage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China\u003c\/p\u003e\n\n\u003cp\u003eDescription: Epithelial cell-derived neutrophil-activating peptide 78 (ENA-78) is a member of the CXC subfamily of chemokines that has the Glu-Leu-Arg (ELR) motif preceding the CXC motif. Similar to other ELR containing CXC chemokines, ENA-78 is a potent neutrophil chemoattractant and activator. Proteolysis of ENA-78 with cathepsin G and chymotrypsin have yielded N-terminally truncated variants with increased biological activities. ENA-70 and ENA-74 represent truncated recombinant ENA-78 variants missing 8 and 4 aa residues, respectively, from the N-terminus. Recombinant ENA-70 and ENA-74 have been shown to have increased potency in neutrophil chemotaxis and myeloperoxidase and elastase release assays.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"5µg","offer_id":42882223964339,"sku":"PR1014-5","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"20µg","offer_id":42882223997107,"sku":"PR1014-20","price":490.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_c0ce5cb5-1f47-4316-bfc7-9187ef8b5c39.jpg?v=1702049582","url":"https:\/\/afsbio.com\/products\/recombinant-human-ena-78-5-78a-a-rhuena-78-cxcl5-pr1014","provider":"AFSBio Inc.","version":"1.0","type":"link"}
