The 2-69 monoclonal antibody specifically binds to 2B4 which is also known as CD244. CD244 is an approximately 63-70 kDa type I transmembrane glycoprotein. It is a SLAM submember (SLAMF4) and CD2 family member of the immunoglobulin superfamily. CD244 was originally identified in the mouse as a non-MHC-restricted cytotoxicity mediator present on NK cells and CD8 T cells. In humans, CD244 is expressed on NK cells, γδ T cells, subsets of effector and memory CD8 T cells, monocytes, eosinophils and basophils. This expression pattern suggests a broad role for CD244 in the regulation of leukocyte activation. CD244 binds CD48 with high affinity. CD244 may serve both stimulatory and inhibitory functions depending on a number of factors. These include the intensity and duration of CD244 interactions with its ligands as well as the presence of other signals generated through different receptor-ligand interactions. 2B4 was clustered as CD244 in the VIIth HLDA workshop. 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.
