In vivo, IL-8 exists in two forms: 77 a.a. produced by endothelial cells, and the more active 72 a.a. produced by monocytes. The receptors of IL-8 are the seven-helical G-protein coupled receptors CXCR1 and CXCR2, exclusively expressed on neutrophils. The functions of IL-8 are to induce rapid changes in cellular shape, activate the integrins, and release the granule contents of neutrophils. Thus, IL-8 can enhance the antimicrobial actions of defense cells.Recombinant human I Interleukin-8\/CXCL8 (rhIL-8) produced in E.coli is a single non-glycosylated polypeptide chain containing 72 amino acids. A fully biologically active molecule, rhIL-8 has a molecular mass of 8.4 kDa analyzed by reducing SDS-PAGE and is obtained by proprietary chromatographic techniques at GenScript.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882243526835,"sku":"BK0111-10","price":217.41,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882243559603,"sku":"BK0111-50","price":691.77,"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_14169930-0f46-4336-a38f-90523160c3e5.jpg?v=1702049936","url":"https:\/\/afsbio.com\/products\/recombinant-il-8-cxcl8-8-79aa-human-bk0111","provider":"AFSBio Inc.","version":"1.0","type":"link"}
