It is a disulfide-linked dimer consisting of two peptides-chain A and chain B. PDGF has three subforms: PDGF-AA, PDGF-BB, PDGF-AB. It is involved in a number of biological processes, including hyperplasia, embryonic neuron development, chemotaxis, and respiratory tubule epithelial cell development. The function of PDGF is mediated by two receptors (PDGFR-α and PDGFR-β).\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eE. coli Expression\u003c\/span\u003e\n\u003cp\u003eRecombinant Platelet-derived growth factor -BB Human protein is produced using a validated E. coli expression system and supplied as lyophilized powder for long-term stability.
