FGF-4 and FGF-3 are located closely on chromosome 11. FGF-4 and its receptors (FGF R1c, 2c, 3c and 4) play an important role in the regulation of embryonic development, cell proliferation, and cell differentiation. FGF-4 is required for normal limb and cardiac valve development during embryogenesis.Recombinant human Fibroblast Growth Factor-4 (rhFGF-4) produced in E.coli is a single non-glycosylated polypeptide chain containing 177 amino acids. A fully biologically active molecule obtained by proprietary chromatographic techniques at GenScript, rhFGF-4 has a molecular mass of 19.4kDa as analyzed by reducing SDS-PAGE.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"5μg","offer_id":42882235728051,"sku":"-5","price":217.41,"currency_code":"CAD","in_stock":true},{"title":"25μg","offer_id":42882235760819,"sku":"-25","price":375.54,"currency_code":"CAD","in_stock":true},{"title":"100μg","offer_id":42882235793587,"sku":"-100","price":1317.65,"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_5eaeaa9b-69ba-4c93-ba9d-192102274e47.jpg?v=1702049799","url":"https:\/\/afsbio.com\/products\/recombinant-fgf-4-human","provider":"AFSBio Inc.","version":"1.0","type":"link"}
