CD132 Mouse anti-Human, Brilliant Violet 421, Clone: AG184, BD

TheAG184 monoclonal antibody specifically binds to the 65-70 kDa common γ subunit (γc) that is shared by the IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21 receptor complexes. The γc receptor is a type 1 transmembrane glycoprotein that is constitutively expressed by most peripheral T and B lymphocytes, NK cells, monocytes and granulocytes. The cytoplasmic domain of the γc chain plays an important role in cytokine-mediated signal transduction. By immunofluorescent staining and flow cytometric analyses, the AG184 antibody has been shown to specifically recognize human γc expressed by cell lines including human γc gene-transfected cell lines which are known to express the human γc chain. The AG184 antibody can bind the γc chain in the receptors complexed with IL-2, IL-4, or IL-7, indicating that the antibody recognizes an epitope which is distinct from the cytokine binding site of the γc chain.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon™ BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon™ BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates.
