SCGF α and β are hematopoietic growth factor that exerts their activity at early stages of hematopoiesis. The SCGFs are non-glycosylated species-specific cytokines that can support growth of primitive hematopoietic cells, and in combination with EPO or GM-CSF, promote proliferation or erthroid or myeloid progenitors, respectively. Recombinant human SCGF-β is a 25.0 kDa polypeptide containing 227 amino acid residues.
Catalog #:

Source :
E.coli
Purity :
Greater than 98% by SDS-PAGE gel and HPLC analyses.
Endotoxin Level :
Endotoxin level is less than 0.1 ng per ug (1EU/ug).
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 7 ng/ml.
