Invitrogen™ CD85k (ILT3) Monoclonal Antibody (ZM4.1), Functional Grade, eBioscience™, Invitrogen™

Mouse Monoclonal Antibody

Description: The monoclonal antibody ZM4.1 recognizes ILT3, also known as CD85k. ILT3 is a member of the large family of ILT molecules (Immunologulin-like Transcripts, Leucocyte Ig-like Receptors (LIRs) and Monocyte/Macrophage Ig-like Receptors (MIRs). ILT3 is a 60kDa transmembrane protein with two Ig domains and ITIMs. Expression is found on monocytes, macrophages, and dendritic cells. High levels of ILT3 expression is also found on plasmacytoid dendritic cells (pDCs). ILT3 expression by DCs has been shown to be required to induce Regulatory Tcells (tregs). Addition of ZM4.1, like ZM3.8, blocks the suppressive function of the Tregs in in vitro culture systems with allogenic DC's. Applications Reported: This ZM4.1 antibody has been reported for use in flow cytometric analysis and has been shown to block Treg function in vitro. Applications Tested: This ZM4.1 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. 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. Endotoxin: Less than 0.001 ng/ug antibody as determined by the LAL assay.
