Attributs du produit: The 6C1 antibody reacts with common epitopes of PIR-A and PIR-B (Paired Immunoglobulin-liked Receptors) in all mouse strains tested (A/J, BALB/cJ, C3H, C57BL/6, DBA/1, DBA/2, NZB, and SJL). PIR-A and PIR-B are type-I transmembrane glycoproteins containing six Ig-like domains. There are multiple PIR-A proteins which are activating receptors by virtue of their intracellular association with the ITAM (Immunoreceptor Tyrosine-based Activation Motif)- containing Fc receptor γ chain (FcRγ) in mast cells and macrophages. FcRγ expression is required for PIR-A cell-surface expression on dendritic cells, B cells, and myeloid lineages. In contrast, PIR-B is an inhibitory receptor which contains various ITIMs (Immunoreceptor Tyrosine-based Inhibitory Motifs) in its cytoplasmic domain. These receptors are expressed on B cells, granulocytes, mast cells, dendritic cells, and monocytes/macrophages, but not on thymocytes, T lymphocytes, erythroid lineage cells, or NK cells. The level of cell-surface expression of these receptors increases as a function of B-cell activation and myeloid- and B-lineage differentiation. The 6C1 antibody immunoprecipitates molecules of 85- and 125- kDa, which correspond to PIRA and PIR-B, respectively. The expression of PIR-A/B on mouse spleen cells. BALB/c splenocytes were preincubated with Mouse BD Fc Block™ (Cat. no. 553141/553142) and stained with purified 6C1 monoclonal antibody (shaded histogram) followed by biotin-conjugated RG11/39.4 mAb (anti-rat IgG1, Cat. no. 553890, both histograms), then Streptavidin-PE (Cat. no. 554061, both histograms). Flow cytometry was performed on a BD FACScan™
