FIGURE: 1 / 1
Description: The BMA12 monoclonal antibody reacts with mouse CD100, also known as Sema4D. Sema4D/CD100 is a 150kDa transmembrane protein expressed constitutively on T cells and is involved in the activation of B cells through its interaction with CD72. Interaction of these two proteins diminishes the negative signaling normally effected by CD72. CD100 is already expressed strongly on resting T cells and somewhat weakly on B cells, but activation upregulates expression on both cell types. Antigen expression has been reported in Spleen, thymus and lymph nodes.
Applications Reported: The BMA12 (BMA-12) antibody has been reported for use in flow cytometric analysis.
Applications Tested: The BMA12 (BMA-12) 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.
Filtration: 0.2 µm post-manufacturing filtered.
Semaphorins are neuronal chemorepellants that direct pioneering neurons during nervous system development. CD100 (also known as semaphorin 4d), a 150 kDa homodimer, is a novel semaphorin that induces B cells to aggregate and improves their viability in vitro. CD100 modifies CD40-CD40L B cell signaling by augmenting B cell aggregation and survival and down regulating CD23 expression. CD72 is a lymphocyte receptor for the class IV semaphorin CD100, which is involved in regulating B cell signaling. CD100 is expressed on resting and PHA stimulated T cells. The protein is weakly expressed on NK cells, EBV transformed B cells, monocytes and tumor/peripheral blood T cell lines, and at higher density on activated T cells and B cells.
