Technical Data
Platelet Derived Growth Factor BB, Recombinant, Human (PDGF-BB)
Growth Factors, Cytokines Storage: -20CShipping: Blue Ice
This polypeptide is composed of two identical polypeptide chains attached by disulfide bonds. As it has been described in the natural product, PDGF-BB is partially clipped at Arg32-Thr33. This cleavage is visible upon reduction of the polypeptide with a reducing agent.


Biological Activity:
The material is fully active as determined by its mitogenic activity measured by stimulation of 3H-thymidine incorporation into human foreskin fibroblast cells.

Storage and Stability:
Lyophilized powder may be stored at -20C. Reconstitute to with sterile dH2O or buffer, aliquot and store at -20C. Reconstituted product is stable for 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
