    Protocol

    Specificity / Sensitivity

    FcγRIIB (D8T4C) Rabbit mAb recognizes endogenous levels of total FcγRIIB protein. Based on western blot analysis of lysates from cells transfected with constructs expressing FcγRIIA or FcγRIIB, FcγRIIB (D8T4C) Rabbit mAb has a strong preference for FcγRIIB and demonstrates weak cross-reactivity with FcγRIIA.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human FcγRIIB protein.

    Background

    FcγRIIB (CD32B) is a low affinity, IgG Fc-binding receptor expressed on B cells, monocytes, macrophages, and dendritic cells (DCs) (1-3). It is the inhibitory Fc receptor and signals through an immunoreceptor tyrosine-based inhibitory motif (ITIM) within its carboxy-terminal cytoplasmic tail (2). Binding of immune complexes to FcγRIIB results in tyrosine phosphorylation of the ITIM motif at Tyr292 and recruitment of the phosphatase SHIP, which mediates inhibitory effects on immune cell activation (2,4). In this way, FcγRIIB suppresses the effects of activating Fc-binding receptors (3). For example, mice deficient for FcγRIIB have greater T cell and DC responses following injection of immune complexes (5,6). In addition, FcγRIIB plays a role in B cell affinity maturation (7). Signaling through FcγRIIB in the absence of signaling through the B cell receptor (BCR) is proapoptotic, while signaling through FcγRIIB and the BCR simultaneously attenuates the apoptotic signal and results in selection of B cells with higher antigen affinity (7).
