Anti-CD3, epsilon (Early T Cell Marker), Phycoerythrin conjugated, clone 5K2

CD3, epsilon, a member of the immunoglobulin superfamily of cell surface receptors, is comprised of five invariable chains ranging in size from 16-28kD and is closely associated with the T cell antigen receptor (TCR). It is expressed on all T cells of all mouse strains. CD3 plays a major role in signaling during antigen recognition, leading to T-cell activation. In the presence of Fc receptor-bearing accessory cells, soluble antibody can activate primed and naïve T cell in vitro. It can also induce redirected lysis of specific target cells by CTL clones and it can block lysis of specific target cells by antigen-specific CTL's. Immobilized antibody can activate both normal T lymphocytes and cloned T cell lines. Under certain conditions, T cell activation by this antibody may result in apoptotic cell death (1-6). Applications: Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry, Flow Cytometry, In vitro depletion of CD3+ cells and In vitro activation of T cells. Other applications not tested. Recommended Dilution: Flow Cytometry: <0.1ug/10e6 cells, Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for 12 months at 4°C. Freezing R-Phycoerythrin (PE) conjugates will result in a substantial loss of activity. PE conjugates are sensitive to light.
