Description

Description: The N28.1 monoclonal antibody recognizes the Fc receptor homolog expressed in B cells (FREB), also know as FCRLA or FcRX. FREB is a member of the family of Fc receptors for IgG (FcRg). Unlike FcRg, FREB lacks a transmembrane sequence and has an intracellular localization. FREB has been detected in proliferating and activated B cells, EBV-transformed B cells, germinal center centroblast, follicular lymphoma and the Burkitt's lymphoma cell line Raji. In contrast with published reports, the N28.1 antibody was also able to detect expression of FREB in resting B cells from normal human blood samples. Applications Reported: This N28.1 antibody has been reported for use in intracellular staining followed by flow cytometric analysis, and immunohistochemical staining. (Fluorochrome conjugated N28.1 is recommended for use in intracellular flow cytometry). Applications Tested: This N28.1 antibody has been tested by intracellular staining followed by flow cytometric analysis of normal human peripheral blood cells. This can be used at less than or equal to 0.03 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

Receptors for the Fc fragment of IgG, or FCGRs (see MIM 146790), are cell surface glycoproteins of the Ig superfamily (IgSF). These receptors mediate phagocytosis of IgG-coated pathogens and promote activation of effector cells, leading to inflammatory responses and antibody-mediated cellular cytotoxicity. All FCGR genes map to human chromosome 1. Additional genes in this region, including FREB, encode FCGR homologs that are selectively expressed in B cells and may be implicated in B-cell development and lymphomagenesis.
