PDGF-BB Protein, Rat

PDGF-BB Protein, Rat is a member of PDGF family, which promotes cell proliferation, survival and migration, through binding to the tyrosine kinase PDGF receptor.

Platelet derived growth factor (PDGF) is a potent mitogen and chemoattractant for mesenchymal and osteogenic cells and stimulates angiogenic molecules which play an essential role in bone regeneration^[1]. Platelet-Derived Growth Factor-BB is a member of PDGF family, which promotes cell proliferation, survival and migration, through binding to the tyrosine kinase PDGF receptor. PDGF-BB exerts beneficial effects on haemorrhagic shock, which are closely related to targeting CX43 to improve vascular reactivity and haemodynamics. PDGF-BB functions in corporal cavernosum smooth muscle cells (CCSMCs) via binding to PDGFR^[2].

The ED₅₀ is <2 ng/mL as measured by 3T3 cells, corresponding to a specific activity of >5.0 × 10⁵ units/mg.

  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of 20 mM acetic acid or 50 mM Tris-HCL, 300 mM NaCl, pH 8.0 or PBS, pH 7.4, 8% trehalose.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in 20mM HAc. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
