The 2.4E6 monoclonal antibody specifically binds to CD212, which is also known as the Interleukin-12 Receptor beta-1 chain (IL12RB1/IL-12RB1/IL-12Rβ1). CD212 serves as a subunit for the functional IL-12 Receptor (IL-12Rβ1-IL-12Rβ2) and IL-23 Receptor (IL-12Rβ1-IL-23R) complexes. CD212 is expressed on T cells, B cells, or NK cells. CD212 is a type I transmembrane glycoprotein that belongs to the hemopoietin receptor superfamily. CD212 is responsible for binding to the IL-12 p40 subunit that is common to the heterodimeric IL-12 and IL-23 cytokines. IL-12 and IL-23 are immunomodulatory cytokines produced mainly by antigen-presenting cells (APC) including monocytes and dendritic cells. These cytokines have overlapping as well as distinct biological activities.
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
