Human CD117 (c-kit) is a transmembrane protein with receptor tyrosine kinase capacity and serves as the receptor for steel factor (SLF). CD117 is expressed on almost all hematopoietic progenitor cells and receptor /ligand interaction is crucial for development of hematopoietic stem cells (2, 3).
Isotype: Murine IgG1
Immunogen: Human MO7e tumor cells
Specificity: Antibody 57A5 recognizes extracellular epitope 2 of the human CD117 molecule of about 150 kd.
Functional Application: Antibody 57A5 does not block binding of SCF (4).
