CD3 Mouse anti-Human, Brilliant Violet 711, Clone: UCHT1, BD

Description

• The UCHT1 monoclonal antibody specifically binds to the human CD3 ε -chain, a 20-kDa subunit of the CD3/T cell antigen receptor complex
• CD3 ε 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 CD3 ε -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 CD3 ε unlike the other CD3 clone, HIT3a, that stains only extracellular CD3 ε
• The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon™ Brilliant Violet™ family of dyes
• This dye is a tandem fluorochrome of BD Horizon™ BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 711-nm
• BD Horizon™ BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor™ 700-like dyes (eg, 712/20-nm filter)
• Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy™5.5 detectors
• However, the spillover can be corrected through compensation as with any other dye combination.
