Description

Mouse Monoclonal Antibody

Description: This B73.1 monoclonal antibody reacts with human CD16, a member of the Fc receptor family also known as Fc gamma RIIIa and Fc gamma RIIIb. This 50-65 kDa receptor is expressed on natural killer cells, neutrophils, monocytes, and macrophages. Crosslinking of CD16 in natural killer cells and monocytes results in activation of the MAPK and PI3K signaling pathways, thus regulating the production of TNF alpha, IL-6, and IL-1 beta. This monoclonal antibody has been shown to block Fc receptor functions. Applications Reported: This B73.1 antibody has been reported for use in functional blocking assays and flow cytometric analysis. Applications Tested: This B73.1 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at less than or equal to 1 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. Storage and handling: Use in a sterile environment. Filtration: 0.2 μm post-manufacturing filtered. Purity: Greater than 90%, as determined by SDS-PAGE. Endotoxin Level: Less than 0.001 ng/μg antibody, as determined by LAL assay. Aggregation: Less than 10%, as determined by HPLC.

CD16, known as Fc gamma receptor III, exists in two distinct isoforms: Fc gamma RIIIA and Fc gamma RIIIB. These isoforms are encoded by the genes FCGR3A and FCGR3B, respectively, which are located on chromosome 1 and share a high degree of similarity. Fc gamma RIIIA is expressed as a polypeptide-anchored form on monocytes, macrophages, and lymphocytes such as natural killer (NK) cells, but not on T or B cells. This receptor recognizes the Fc portion of immunoglobulin G (IgG) and is involved in the clearance of immune complexes from circulation. Upon binding IgG, Fc gamma RIIIA activates signal transduction pathways that result in antibody-dependent cell-mediated cytotoxicity (ADCC), phagocytosis, cytokine release, and antigen presentation. Fc gamma RIIIB is expressed on polymorphonuclear neutrophils (PMN) as a glycosylphosphatidylinositol (GPI)-anchored form. It plays a role in similar immune functions, including cellular-mediated cytotoxicity and enhancement of virus infections. Mutations in the FCGR3A gene have been associated with Immunodeficiency 20 and linked to susceptibility to recurrent viral infections, systemic lupus erythematosus, and alloimmune neonatal neutropenia. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. Diseases associated with FCGR3A include Immunodeficiency 20 and Herpes Zoster.
