Background: CD117 (c-Kit, stem cell growth factor receptor (SCFR)), is a receptor tyrosine kinase protein activated by stem cell factor (c-Kit ligand) leading to cell survival, proliferation, and differentiation. CD117 is expressed on pluripotent hematopoietic progenitor cells, mast cells, and can be used for tumor identification, for example, for diagnosis of gastrointestinal stromal tumors (GIST). Mutations within the gene are associated with GIST, melanoma, acute myeloid leukemia (AML), and mast cell disease. Many approved kinase inhibitors inhibit CD117’s kinase activity and additional drug development is on-going. CD117 activation leads to mobilization of progenitor cells from the bone marrow to the bloodstream.

Validation: Each lot of conjugated CD117 antibody is quality control tested by MIBIscope™ analysis of stained tissue microarrays using the appropriate positive and negative tissue field of views and are pathologist verified.

Recommended Usage: 1 uL of CD117 antibody per 100 uL staining volume using the MIBI™ Staining Protocol.
For optimal results, antibody should be titrated for each desired application.  Suggested starting range is 1:100.
