Description
The UCHT1 monoclonal antibody specifically binds to the human CD3ε-chain, a 20-kDa subunit of the CD3/T cell antigen receptor complex. CD3ε is expressed on 70-80% of normal human peripheral blood lymphocytes and 60-85% of thymocytes. Studies from the HLDA Workshop show that this antibody is mitogenic for CD3ε-positive cells when used in conjunction with costimulatory agents such as pokeweed mitogen or anti-CD28 antibody. CD3 plays a central role in signal transduction during antigen recognition. The UCHT1 antibody stains both surface and intracellular CD3ε unlike the other CD3 clone, HIT3a, that stains only extracellular CD3ε.
The antibody is conjugated to BD Horizon™ V500, which has been developed for use in multicolor flow cytometry experiments and is
available exclusively from BD Biosciences. It is excited by the Violet laser with an Ex max of 415nm and Em Max at 500 nm. BD Horizon V500 conjugates emit at a similar wavelength to AmCyan yet exhibit reduced spillover into the FITC channel. For more information on BD Horizon V500, visit bdbiosciences.com/colors.
When compensating dyes in this spectral range (such as Horizon™ V500 and AmCyan), the most accurate compensation can be obtained using single stained cellular controls. Due to spectral differences between cells and beadsin this channel, using BD CompBeads can result in spillover errors for V500 and AmCyan reagents.Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended.Different V500 reagents (e.g., CD4 vs. CD45) can have slightly different fluorescence spillover levels. Therefore, it may also be necessary to use clone specific compensation controls when using these reagents.
