CD267 (TACI) Rat anti-Mouse, Brilliant Violet 421, Clone: 8F10, BD Optibuild™

Description

The 8F10 monoclonal antibody specifically recognizes CD267 which is also known as transmembrane activator and calcium-modulating and cyclophilin ligand interactor(transmembrane activator and CAML interactor or TACI). CD267 is encoded by Tnfrsf13b /(tumor necrosis factor receptor superfamily member 13B). CD267 is a type III transmembrane protein receptor that binds to the ligands BAFF (BLyS), and APRIL. BAFF overproduction is associated with lupus erythematosus and Sjφgren's disease, two systemic autoimmune diseases. CD267 is expressed most notably on maturing subsets of splenic B cells such as transition type 2 (T2) and marginal zone (MZ) B cells and also in activated T-cells. In CD267 deficient mice, B cell numbers are increased and mice develop autoimmune disorders suggesting that CD267 plays a role in B cell regulation.

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 407nm and Em Max at 421nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates. BV421 is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences. Conjugates are typically 10 times brighter than Pacific Blue™ conjugates and are often as bright as or brighter than PE conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.
