The YB5.B8 monoclonal antibody specifically binds to CD117. CD117, also known as c-Kit, is a 145 kDa cell-surface glycoprotein with tyrosine kinase activity. CD117 is present on hematopoietic progenitor cell subsets, thymocytes, mast cells, hepatocytes and histiocytes.CD117 serves as a cytokine receptor for steel factor (SLF), also known as stem cell factor (SCF) or mast cell growth factor (MGF). The interaction of c-Kit and SLF is crucial to hematopoiesis, mast cell differentiation, melanogenesis, and germ cell development. The ability ofthe YB5.B8 antibody to block the binding of c-Kit ligand is still controversial. The antibody was conjugated to Brilliant Violet 421 and has been developed in collaboration with Sirigen. With an Ex Max of 407-nm and Em Max at 421-nm, Brilliant Violet 421 can be excited by the violet laser and detected in the standard Pacific Blue filter set (eg, 450/50-nm filter). Brilliant Violet 421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.Host Species: MouseClone: YB5.B8Isotype: IgG1, κSpecies Reactivity: HumanFlow Cytometry
