背景 | Platelet-Derived Growth Factor (PDGF)-BB is synthesized as a 35 kDa, 241 amino acid (aa) prepro-precurser. It contains a signal peptide, an N-terminal prodomain, a mature region, and a C-terminal prodomain (1-4). The propercursor is initially dimerized and then intracellulary processed twice. The N-terminal prodomain is cleaved first, followed by cleavage of the C-terminal prodomain. The resulting mature region is 16-17 kDa in size (or 29-32 kDa as a homodimer) (4). Mature human PDGF-B shares 89% aa sequence identity with mouse mature PDGF-B. PDGF-BB is expressed by hepatocytes and nonresorbing osteoclasts, generating osteoblasts and bone formation (4, 5). It is also produced by platelets, macrophages, and mast cells. At sites of injury, it promotes neutrophil and macrophage infiltration for debridement, fibroblast secretion of new extracellular matrix, and IGF-I-mediated re-epithelialization (6, 7). The traditional receptor for PDGF is either a homodimer or heterodimer created from two type I transmembrane RTKs, PDGF R alpha and PDGF R beta (8, 9). PDGF-BB has been shown to bind the alpha alpha homodimer, alpha beta heterodimer, and the beta beta homodimer in vitro, and act through the beta beta homodimer in vivo (8, 10). |

不含载体 | What does CF mean? CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA. What formulation is right for me? |

Both Biotinylated Recombinant Human PDGF-BB (Catalog # BT220) and unlabeled Recombinant Human PDGF-BB (Catalog # 220-BB) stimulate NR6R‑3T3 mouse fibroblast cell proliferation. The ED50 for this effect is typically 1.5-6 ng/mL. The similarity in activity highlights that the biotinylated protein is fully functional. |
