CD16/CD32 Monoclonal Antibody (93), Super Bright™ 600, eBioscience™, Invitrogen™

Description

Description: The 93 monoclonal antibody reacts with an epitope shared by mouse CD16 and CD32. CD16 (Fc gamma III Receptor) and CD32 (Fc gamma II Receptor) are the low affinity receptors for the mouse IgG Fc portion and are expressed by B cells, monocyte/macrophages, NK cells, and neutrophils. Applications Reported: This 93 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 93 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.125 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. Super Bright 600 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 600 nm. We recommend using a 610/20 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome. When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Staining Buffer (Product No. SB-4400) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer for more information. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation.

CD16 is a 50-65 kDa cell surface molecule that exists in two forms - a transmembranous form expressed by natural killer (NK) cells, and some T cells and a phosphatidylinositol linked form expressed by granulocytes. CD16 is a low affinity receptor for IgG (FcR III), and is an important receptor mediating ADCC (antibody dependent cell mediated cytotoxicity) by NK cells. IN comparison, CD32 is a 40 kD glycoprotein that acts as a low affinity receptor for IgG (also known as Fc gamma RII), and mediates several functions including endocytosis, activation of secretion, cytotoxicity and immunomodulation. CD32 is expressed by B cells, monocytes, granulocytes and platelets. Further, CD32 is involved in the phagocytosis of immune complexes, the regulation of antibody production by B-cells, and variations of the CD32 gene may increase vulnerability to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms of CD32 have been found.
