Mouse Monoclonal Antibody

Description: The SH2.1 monoclonal antibody reacts with mouse siglec-G, which is also known as sialic acid-binding immunoglobulin-like lectin-G. Siglec-G is an inhibitory receptor that is expressed in a B cell-specific manner with B1 B cells expressing the highest levels of siglec-G. When overexpressed, siglec-G inhibits B cell receptor-mediated calcium signaling. Siglec-G-deficient mice show a massive expansion of the B1a cell population as well as higher titers of natural IgM antibodies. Siglec-G-deficient B1a cells show a lower level of spontaneous apoptosis and a prolonged life span, which may result from higher expression levels of the transcription factor NFATc1. Siglec-G-dependent negative regulation exists in B1 cells, which may explain the naturally muted signaling response of B1 cells. Applications Reported: This SH2.1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This SH2.1 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. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.
