||Stem Cell Factor Receptor (SCFR) is a member of the receptor tyrosine kinase family. Binding of SCFR to its ligand Stem Cell Factor (PE-1242-5) induces receptor dimerization, autophosphorylation and signal transduction. SCFR is essential for the development of normal hematopoietic cells and plays an important role in the survival, proliferation and differentiation of mast cells, melanocytes and germ cells.

||Human - A DNA sequence encoding the signal peptide and extracellular domain of human Stem Cell Factor Receptor (amino acids 1-520) was expressed in modified human 293 cells.
||Under reducing conditions SCFR migrates as a broad band between 65 and 100 kDa on SDS-PAGE due to post-translational modifications. The unmodified SCFR polypeptide has a predicted monomeric molecular mass of 55.9 kDa.
SCFR separates into a number of glycoforms with a pI between 4 and 7 on 2D PAGE due to post-translational modifications. The unmodified SCFR has a predicted pI of 6.1.

||The ED50 of SCFR is typically 2-4 ug/ml from its ability to neutralise SCF mediated
proliferation of the human growth dependent M-07e cell line.
||Purified SCFR consists of approximately 15-45% carbohydrate by weight. When reconstituted in 0.5 ml sterile phosphate-buffered saline, the solution will contain
1% human serum albumin (HSA) and 10% trehalose.
||It is recommended that 0.5 mL of sterile phosphate-buffered saline be added to the vial.
||Lyophilized products should be stored at 2 to 8C. Following reconstitution, short-term storage at 2-8C and longer-term storage of aliquots at -18 to -20C is recommended. Repeated freeze/thawing is not recommended.
