Description

The Eat-2 (EAT2) monoclonal antibody reacts with mouse CD81, a molecule also known as TAPA-1. CD81 is expressed on CD4⁺CD8⁺ thymocytes and broadly in the periphery with high level expressed by B cells, NK cells, macrophages and dendritic cells and lower level on resting T cells. Activation of T cells induces upregulation of CD81. CD81 is involved in homotypic adhesion of B and T cells as well as costimulation of T cells. The Eat-2 antibody is reported to cross-react with rat CD81.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The Eat-2 (EAT2) antibody has been reported for use in flow cytometric analysis.

Applications Tested

The Eat-2 (EAT2) antibody has been tested by flow cytometric analysis of mouse thymocyte and splenocyte suspensions. This can be used at less than or equal to 0.5 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.
