BD Pharmingen™ PE Rat anti-Human CD267
Clone 1A1-K21-M22 (also known as 1A1) (RUO)

Flow cytometric analysis of PE-conjugated anti-Human CD267 in human peripheral blood lymphocytes. Human peripheral blood lymphocytes were stained with APC-conjugated anti-human CD19 (Clone HIB19; Cat. No. 555415) and PE-conjugated anti-human CD267 antibody (Clone 1A1-K21-M22, Cat. No. 558414; right panel) or PE -conjugated rat IgG2a (Clone R35-95, Cat. No. 553930; left panel). Flow cytometry was performed on a BD™ FACSCalibur flow cytometry system and the dot plots were derived from the gated events based on light scattering characteristics of lysed whole blood.

The 1A1-K21-M22 monoclonal antibody specifically binds to CD267 which is also known as TACI (Transmembrane Activator and CAML Interactor). CD267 is a member of the of the Tumor Necrosis Factor Receptor (TNFR) Superfamily and is encoded by the TNFRSF13B gene. This 32 kDa type III transmembrane protein receptor binds to the ligands, BAFF (TNFSF13B/BLyS/CD257) and APRIL (TNFSF13/CD256). Ligand-bound CD267 transduces signals leading to the activation of transcription factors including NFAT, AP1, and NF-kappa-B. CD267 is expressed most notably on maturing subsets of B cells and myeloma cells. In CD267 deficient mice, B cell numbers are increased and mice develop autoimmune disorders suggesting that CD267 plays an important role in the regulation of B cell homeostasis.
