Description

The 2E7 monoclonal antibody reacts with mouse CD103, the α_E integrin. CD103 non-covalently associates with integrin β₇ and is expressed on all intraepithelial lymphocytes, a small subset of peripheral lymphocytes, and dendritic epidermal T cells (DEC). 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. The 2E7 antibody has been reported for use in flow cytometric analysis.

Applications Tested

The 2E7 antibody has been tested by flow cytometric analysis of mouse splenocyte suspensions. 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.
