名称：原装供应| Recombinant Human SCGF-beta (formerly SCGF)
Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses.
Description: Synonyms: Stem Cell Growth Factor-β. 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. Determined by its inhibitory effect on the proliferation of TF-1 cells previously grown in media containing GM-CSF. Recombinant human SCGF-β is a 25.0 kDa polypeptide containing 227 amino acid residues.
Biological Activity: The ED50 for this effect was observed at 7 ng/ml. Source: E.coli. SCGF-α and -β are hematopoietic growth factor that exerts their activity at early stages of hematopoiesis.
