Platelet-derived Growth Factor AA Human Recombinant, Yeast ( PDGF AA Human, Yeast )

Data sheet

Formulation

The protein was lyophilized with 20mM sodium phosphate buffer.

Solubility

It is recommended to reconstitute the lyophilized PDGF-AA in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 98.0% as determined by SDS-PAGE.

Description

PDGF-AA Human Recombinant produced in Yeast is a homodimeric, glycosilated, polypeptide chain containing 2 x 110 amino acids and having a total molecular mass of 34 kDa. PDGF-AA is purified by proprietary chromatographic techniques.

Protein Background

PDGF-AA, PDGF-BB and PDGF-AB, are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGF is stored in platelet alpha-granules and released upon platelet

Expression host

Pichia Pastoris.

Synonyms

Glioma-derived growth factor, GDGF, Osteosarcoma-derived Growth Factor, ODGF, PDGF-AA, PDGF-1.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized PDGF-AA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PDGF-AA should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to ad

Biological Activity

The ED50 was found to be 1ng/ml corresponding to a Specific Activity of 1,000,000IU/mg calculated by the ability to stimulate the proliferation of mouse 3T3 fibroblasts (PNAS 94, 10205, 1997. Biochemistry, 1996, 35, 12077).
