Description

The YB5.B8 monoclonal antibody reacts with human CD117, also known as c-Kit , Steel factor receptor and stem cell factor receptor. A member of the tyrosine kinase receptor family, this 145 kDa molecule is expressed by hematopoietic progenitor cell subsets and mast cells. The interaction of c-Kit and Steel factor promotes proliferation and differentiation of hematopoietic progenitor cells and mast cell differentiation. CD117 is also expressed by melanocytes and plays a role in signaling and activation of these cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. YB5.B8 has been reported for use in flow cytometric analysis.

Applications Tested

This YB5.B8 antibody has been tested by flow cytometric analysis of the TF-1 cell line; a human erythroleukemia cell line. This can be used at less than or equal to 1 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
