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™ 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.
