CD273 (B7-DC) Monoclonal Antibody (122), Super Bright™ 436, eBioscience™, Invitrogen™

Description

Description: The 122 monoclonal antibody reacts with mouse B7-DC, also known as PD-L2. B7-DC, a member of the B7 family, has a predicted molecular weight of approximately 25 kDa and belongs to the Ig superfamily. The mouse B7-DC has a short cytoplasmic tail (4aa). B7-DC is primarily expressed by subpopulations of dendritic cells and monocytes/macrophages in the mouse. Although B7-DC has structural and sequence similarities to the B7 family, it does not bind CD28/CTLA-4, rather it is a ligand for PD-1. The interactions between PD-1 and B7-DC/PD-L2 have been reported to be involved in costimulation or suppression of T cell proliferation depending on state of cellular activation. 122 has been demonstrated to block binding of TY25 (Cat. No.14-5986), another mAb specific for mouse B7-DC. Applications Reported: This 122 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 122 antibody has been tested by flow cytometric analysis of bone marrow derived dendritic cells. This may be used at less than or equal to 1.0 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 436 can be excited with the violet laser line (405 nm) and emits at 436 nm.
