Description

The B-Ly7 monoclonal antibody reacts with human CD103, the α_E integrin. CD103 non-covalently associates with integrin β₇. CD103 is expressed mainly on intraepithelial lymphocytes and a small subset of peripheral lymphocytes. CD103 is also expressed by hairy cell leukemia (HCL) and by some chronic B cell lymphocytic leukemias. In vitro stimulation of human T cells with mitogens induces upregulation of CD103. Epithelial cell antigen, E-cadherin, binds to CD103 and mediates homing of lymphocytes to the intestinal epithelium.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This B-Ly7 antibody has been reported for use in flow cytometric analysis.

Applications Tested

This B-Ly7 antibody has been pre-titrated and tested by flow cytometric analysis of 2-3 day PHA-activated human peripheral blood leukocytes. This can be used at 20 μl (0.5 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume).
