Recombinant SCF, Human (P. pastoris-expressed)

• Catalog Number: orb1494611
• Category: Proteins
• Description: Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity during the early stages of hematopoiesis. SCF stimulates the proliferation of myeloid, erythroid, and lymphoid progenitors in bone marrow cultures and has been shown to act synergistically with colony stimulating factors.Recombinant human Stem Cell Factor (rhSCF) produced in Pichia pastoris is a glycosylated polypeptide chain of 165 amino acids. A fully biologically active molecule, rhSCF has a molecular mass of ~20kDa analyzed by reducing SDS-PAGE and is obtained by proprietary refolding and chromatographic techniques at GenScript.
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• MW: ~20 kDa, observed by reducing SDS-PAGE.
