avoid freeze/thaw cycles

Shelf Life: 12 months

Molecular Weight: 18.4 kDa

Accession number: P21581

Accession number: P21581

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilized (CSF was lyophilized from 0.02% NaHCO3)

Solubility: It is recommended to reconstitute the lyophilized SCF in sterile bidest H2O not less than 100 μg/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Activity: ED50: < 10 ng/ml, corresponding to a specific activity of 105 IU/mg, determined by the dosedependent stimulation of the proliferation of human MO7e cells.

Description:
Stem Cell Factor (SCF) plays an important role in hematopoiesis and survival, proliferation, and differentiation of mast cells, melanocytes, and germ cells. SCF mediates its biological effects by binding to and activating a receptor tyrosine kinase designated c-kit or SCF receptor (SCFR). SCF is also known as mast cell growth factor (MCGF), steel (Sl) factor (SLF), or kit ligand (KL). Recombinant rat SCF produced in E. coli is a single, non-glycosylated polypeptide chain containing 165 (26-189)amino acids.
