MHC Class II (I-A) Rat anti-Mouse, FITC, Clone: NIMR-4, eBioscience
Rat Monoclonal Antibody
Manufacturer: Invitrogen 11532282
Description: The monoclonal antibody NIMR-4 reacts specifically with a non-polymorphic I-A-encoded epitope on MHC Class II antigens. Class II antigens are predomitly expressed on antigen-presenting cells including B lymphocytes, macrophages, dendritic cells and certain epithelial cells. MHC Class II molecules are important for the selection of the TCR repertoire during the processes of positive and negative selection. MHC Class II expression is required for the positive selection of CD4+ T cells. Applications Reported: This NIMR-4 antibody has been reported for use in flow cytometric analysis. Applications Tested: This NIMR-4 antibody has been tested by flow cytometric analysis of mouse splenocytes. 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. Excitation: 488 nm; Emission: 520 nm; Laser: Blue Laser. Filtration: 0.2 µm post-manufacturing filtered.MHC class II molecules are heterodimers of non-covalently associated alpha (31-34 kDa) and beta (26-29 kDa) chains. Major histocompatibility complex class II antigen presentation requires the participation of lysosomal proteases in two convergent processes. First, the antigens endocytosed by the antigen presenting cells must be broken down into antigenic peptides. Second, class II molecules are synthesized with their peptide-binding site blocked by invariant chain (Ii), and they aquire the capacity to bind antigens only after Ii has been degraded in the compartments where peptides reside. MHC class II molecules present exogenously derived antigen to CD4+ T lymphocytes, which are usually T helper cells. CD4 interacts with non-polymorphic residues of MHC class II.
