Description

The UCHT1 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 via immobilized UCHT1 initiates an intracellular biochemical pathway resulting in cellular activation and proliferation.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The UCHT1 antibody has been reported for use in flow cytometric analysis, and immunohistochemical staining. UCHT1 has also been reported in activation of T cells. (Please use Functional Grade purified UCHT1, cat. 16-0038, in functional assays.)

Applications Tested

The UCHT1 antibody has been tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at less than or equal to 1 μg per 100 μl blood (or per 1 million cells in 100 μl total staining volume). It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
