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

For research use only, not for diagnostic or therapeutic use. 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 splenocyte suspension. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
