CD274 (PD-L1, B7-H1) Monoclonal Antibody (MIH1), Functional Grade, eBioscience™, Invitrogen™

Mouse Monoclonal Antibody

The MIH1 monoclonal antibody reacts with human B7-H1, also known as PD-L1. B7-H1, a member of the B7 family, has a predicted molecular weight of approximately 40 kDa and belongs to the Ig superfamily. B7-H1 is expressed on a majority of leukocytes. B7-H1 is a ligand for PD-1. Interaction of PD-1 with either PD-L1 (B7-H1) or PD-L2 (B7-DC) results in inhibition of T and B cell responses. MIH1 is reported to be a blocking antibody. Applications Reported: The MIH1 antibody has been reported for use in flow cytometric analysis. It has also been reported in blocking in in vitro functional assays. Applications Tested: The MIH1 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.
