Description

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, immunoprecipitation, and immunohistochemical staining. It has also been reported for use in neutralization of mouse CD100. (Please use Functional Grade purified BMA12, Product # 16-1001, in functional assays). 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 0.25 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. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm p...

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.
