For in vitro use only!

Shipping: shipped at ambient temperature

Storage Conditions: store at -20 °C
avoid freeze/thaw cycles

Shelf Life: 12 months

Molecular Weight: 29 kDa

Accession number: P04085

Accession number: P04085

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilised

Solubility: It is recommended to reconstitute the lyophilised PDGF-AA in sterile bidest H2O not less than 100 μg/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Activity: ED50: < 1 ng/ml, corresponding to a specific activity of 1 x 106 IU/mg, calculated by the dosedependent proliferation of murine BALB/c 3T3 indicator cells (measured by 3H-thymidine uptake).

PDGF is a mitogenic peptide growth hormone carried in the alpha-granules of platelets. It is released when platelets adhere to traumatized tissues. Connective tissue cells near the traumatized region respond by initiating the process of replication. The synthesis of PDGF can be induced by Interleukin-1, Interleukin-6, TNF-α, TGF-β and EGF. Recombinant Human Platelet Derived Growth Factor-AA is a homodimeric, non-glycosylated, polypeptide chain containing 2 x 125 amino acids and having a total molecular mass of 28.51 kDa. Recombinant PDGF-AA is purified by proprietary chromatographic techniques.

Endotoxin: Less than 0.1 ng/μg (IEU/μg) of PDGF-AA.
