Description
The monoclonal antibody 162 recognizes CRACC (CD2 like receptor for activating cytotoxic cells) also known as CD319 and CS1. It is a member of the SLAM receptor family. CRACC is a 66kDa glycosylated transmembrane protein which contains a cytoplasmic ITSM domain (Immunoreceptor Tyrosine-based Switch Motif). It is this domain, found in other proteins such as CD244 and NTB-A, that interacts with SH2 containing proteins such as SAP. Interestingly the ITSM domain in CRACC is SAP independent. Instead EAT-2 acts as the signaling molecule for CRACC. This has profound impact for patients with X-linked lymphoproliferative disease (contains a SAP mutation). It should be noted that a splice variant has been reported which deletes the ITSM domain.
Applications Reported
For research use only, not for diagnostic or therapeutic use. This 162 antibody has been reported for use in flow cytometric analysis, and immunoprecipitation.
Applications Tested
This 162 antibody has been tested by flow cytometric analysis of human peripheral blood cells. 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.
