KIT，also known asmast/stem cell growth factor receptor Kit isoform 1，is a cytokine receptor that is expressed not only in hematopoietic stem cells but also in other cell types. It binds to receptor tyrosine kinase type III，a stem cell factor，also called a rigid factor or c-kit ligand. When this receptor binds to stem cell factor （SCF），it forms a dimer that activates intrinsic tyrosine kinase activity，which，in turn，phosphorylates and activates signaling molecules that propagate signals in cells. This receptor protects vascular smooth muscle cells from apoptosis and helps restore cardiac function after myocardial infarction.Source：Recombinant protein corresponding to aa24-188 from human KIT，fused to His-Tag at C-terminal，expressed in insect cell.Molecular Weight： ~57.1kD （507aa），50-70kD （SDS-PAGE under reducing conditions）Endotoxin： <1EU/1ug （determined by LAL method）Storage and Stability：May be stored at 4°C for short-term only.
