CD69 Hamster anti-Murine, Brilliant Ultraviolet 737, Clone: H1.2F3, BD Horizon™

Description

• The H1.2F3 monoclonal antibody specifically binds to CD69 (Very Early Activation antigen), an 85 kDa disulfide-linked homodimer of differentially glycosylated subunits
• CD69 is a C-type lectin, most closely related to the NKR-P1 and Ly-49 NK cell-activation molecules
• Its expression is rapidly induced upon activation of lymphocytes (T, B, NK, and NK-T cells), neutrophils, and macrophages
• CD69 is expressed also on thymocytes that are undergoing positive selection; its role in that process is unclear
• H1.2F3 mAb augments PMA-induced T-cell stimulation and IFN- γ-induced macrophage stimulation
• IL-2-activated NK cells express CD69, and H1.2F3 mAb induces redirected lysis of FcR-bearing target cells by NK cells
• The antibody was conjugated to BD Horizon BUV737 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes
• This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348-nm and an acceptor dye with an Em Max at 737-nm
• BD Horizon Brilliant BUV737 can be excited by the ultraviolet laser (355 nm) and detected with a 740/35 filter
• Due to the excitation of the acceptor dye by other laser lines, there may be significant spillover into channels detecting Alexa Fluor™ 700-like dyes (e.g., 712/20-nm filter).
