Reconstitution Reconstitute the lyophilized recombinant Human Platelet-derived Growth Factor-BB (rHuPDGF-BB) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1 % BSA. Storage & Stability Lyophilized recombinant Human Platelet-derived Growth Factor-BB (rHuPDGF-BB) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Recombinant Human Platelet-derived Growth Factor-BB is the most active PDGF isoform, binds to PDGF receptor, promotes diverse cell types proliferation and osteogenesis, and further stimulates bone formation in fracture or defect. Platelet-derived growth factor-BB (PDGF-BB) is primarily secreted from platelet α-granules and is the most active PDGF isoform in bone and other connective tissue as it can bind to all known PDGF receptors. PDGF-BB plays an important role in bone regeneration by inducing mitogenesis, chemotaxis, extracellular matrix formation, and vascularization[1]. Recombinant Human Platelet-derived Growth Factor-BB (rhPDGF-BB) accelerates tendon healing by improving matrix remodeling, increased collagen synthesis, and increased cell proliferation. Recombinant Human Platelet-derived Growth Factor-BB is also efficacious in a non-ruptured, degenerated, tendinopathy model. Furthermore, Recombinant Human Platelet-derived Growth Factor-BB addresses chronic tendinopathies by inducing proliferation and migration of progenitor cells and tenocytes, which stimulate structural repair of the degenerated tendon[2]. |
