Description

---

The eBio500A2 monoclonal antibody reacts with the 25 kD epsilon subunit of the mouse CD3 complex. CD3 subunits γ, δ and ε are 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, as well as NKT cells. Binding of eBio500A2 to CD3 initiates the intracellular biochemical pathway resulting in cellular activation and proliferation. The 500A2 antibody is able to partially cross-block the 17A2 and 145-2C11 antibodies, indicating that all three of these anti-CD3 antibodies recognize distinct but overlapping epitopes.

---

Applications Reported

---

For research use only, not for diagnostic or therapeutic use. The eBio500A2 antibody has been reported for use in flow cytometric analysis. It has also been reported for use in in vitro activation of mouse T cells. (Please use Functional Grade purified eBio500A2 in functional assays).

---

Applications Tested

---

This eBio500A2 (500A2) 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.
