85-1370-13　Stem Cell Growth Factor beta, Recombinant, Human (SCGFb) 2ug　S7973-30

特徴

• Stem Cell Growth Factor alpha and beta are hematopoietic growth factors that exert 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 SCGFb is a 25kD polypeptide containing 227 amino acid residues.
• Endotoxin:≤0.1ng/ug (1EU/ug).
• Biological Activity:Determined by the dose dependant stimulation of the proliferation of human TF-1 cells previously grown in media containing GM-CSF. The ED50 for this effect was observed is ≤7ng/ml.
