PDGF BB Human, Yeast

Data sheet

Formulation

The PDGF-BB was lyophilized from 0.2 um filtered solution in 20mM sodium phosphate in absence of any carrier protein.

Solubility

It is recommended to reconstitute the lyophilized Platelet-derived Growth Factor-BB 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

Platelet-Derived Growth Factor BB Human Recombinant is a glycosylated homodimer produced in Saccharomyces cerevisiae, containing 2x109 amino acids and having a molecular mass of 32kDa. PDGF-BB is purified by proprietary chromatographic techniques.

Protein Background

PDGF-BB is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer

Expression host

Saccharomyces cerevisiae.

Synonyms

Glioma-derived growth factor, GDGF, Osteosarcoma-derived Growth Factor, ODGF, SIS, SSV, PDGF2, c-sis, FLJ12858, PDGF-BB, PDGF B-chain, Platelet-derived growth factor beta polypeptide, Becaplermin.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Platelet-derived Growth Factor BB although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PDGF BB should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent free

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Leu-Gly-Ser-Leu.

Biological Activity

The ED50, as measured by its ability to stimulate proliferation of mouse 3T3 fibroblasts is typically 1 ng/ml, corresponding to a Specific Activity of 1,000,000IU/mg.
