PDGF-BB Protein, Mouse

PDGF-BB Protein, Mouse is an active PDGF isoform, used in cell culture applications.

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].

The ED₅₀ is <2.5 ng/mL as measured by 3T3 cells, corresponding to a specific activity of >4 × 10⁵ units/mg.

Approximately 24.7 kDa

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

Lyophilized powder

Lyophilized after extensive dialysis against 10 mM Sodium Citrate, pH 3.0.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. 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.
