Endotoxin level is <0.1 ng/ug of protein (<1 EU/ug).
Determined by the dose-dependent stimulation of the proliferation of Balb/c 3T3 cells. The expected The ED50 for this effect is 15-20 ng/mL.
Activity assay SDS-PAGE The optimal working dilution should be determined by the end user.
Lyophilized from 5mM Sodium Citrate, pH 3.0.
Store at -20°C. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
The protein encoded by this gene 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 core motif of eight cysteines. This gene product appears to form only homodimers. It differs from the platelet-derived growth factor alpha and beta polypeptides in having an unusual N-terminal domain, the CUB domain. [provided by RefSeq
