The TUGh4 monoclonal antibody specifically binds to CD132. CD132 is a 65-70 kDa type 1 transmembrane glycoprotein that is encoded by the IL2RG (interleukin 2 receptor, gamma) gene. CD132 is also known as the common γ subunit (γc) and is shared by the IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21 receptor complexes. CD132 is broadly 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. Mutation of the IL2RG gene results in X-linked severe combined immunodeficiency (XSCID). The TUGh4 antibody recognizes a different epitope from that recognized by the CD132-specific clone, AG184.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
