Technical Data
Stem Cell Growth Factor alpha, Recombinant, Human (SCGFa)
Molecular Biology Storage: -20CShipping: Blue Ice
Stem Cell Growth Factor alpha (SCGF-alpha)is a newly discovered hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. Human SCGF-alpha is a non-glycosylated 33.9kD species-specific cytokine that can support growth of primitive hematopoietic cells, and in combination of EPO or GM-CSF, it promotes proliferation of erythroid and myeloid progenitors, respectively.

Biological Activity:
Determined by its inhibitory effect on the proliferation of TF-1 cells previously grown in media containing GM-CSF. The ED50 for this effect was observed at 2.5 ng/ml.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O, carrier protein. Aliquot to avoid repeated freezing and thawing. 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.
