Description: The 14-4-4S monoclonal antibody reacts with the mouse and rat major histocompatibility complex class II, I-E subregion-encoded glycoprotein in mice strains of H-2^k, H-2^d, H-2^p and H-2^r. H-2^b, H-2^f and H-2^s haplotypes do not express the I-E antigen. MHC class II is present on B cells, monocytes, macrophages, and dendritic cells. The 14-4-4S mAb has been reported to block antigen presentation in in vitro assays. This antibody cross-reacts with rat. Applications Reported: 14-4-4S has been reported for use in flow cytometric analysis. Applications Tested: The 14-4-4S antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.06 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: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.MHC (major histocompatibility complex) class II molecules are transmembrane glycoproteins expressed on the surface of professional antigen-presenting cells, such as macrophages, dendritic cells and B cells. Before their exposition on the cell surface, the MHC class II molecules react with endocytosed exogenous antigens, which are then presented to the T cells. The antigen-binding grove between MHC class II alpha and beta chain is open at both ends and is 15-24 amino acid residues long.
