|Description||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.|
|BiologicalActivity||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.|
|Authenticity||Verified by N-terminal and Mass Spectrometry analyses (when applicable).|
|Endotoxin||Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg).|
|Protein Content||Verified by UV Spectroscopy and/or SDS-PAGE gel.|
|Precautions||Recombinant Human SCGF-β is for research use only and not for use in diagnostic or therapeutic procedures.|
