Description

The HIT3a monoclonal antibody reacts with human CD3e, a 20 kDa subunit of the TCR complex. Along with the other CD3 subunits γ and δ, the ε chain is required for proper assembly, trafficking and surface expression of the TCR complex. CD3 is expressed by thymocytes in a developmentally regulated manner and by all mature T cells. Crosslinking of TCR with HIT3a initiates an intracellular biochemical pathway resulting in cellular activation and proliferation.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The HIT3a antibody has been reported for use in flow cytometric analysis.

Applications Tested

This HIT3a antibody has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at 20 μl (1 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume).
