Invitrogen™ CD4 Monoclonal Antibody (RM4-5), APC, eBioscience™, Invitrogen™

Rat Monoclonal Antibody

Description: The RM4-5 monoclonal antibody reacts with the mouse CD4 molecule, a 55 kDa cell surface receptor expressed by a majority of thymocytes, subpopulation of mature T cells and dendritic cells. CD4 binds to MHC class II on the surface of antigen presenting cells and plays an important role both in T cell development and in optimal functioning of mature T cells. In T cells, CD4 associates with protein tyrosine kinase p56lck through its cytoplasmic tail. Binding of RM4-5 is blocked by GK1.5. Applications Reported: The RM4-5 antibody has been reported for use in flow cytometric analysis. Applications Tested: The RM4-5 antibody has been tested by flow cytometric analysis of mouse thymocyte or splenocyte suspensions. This can be used at less than or equal to 0.125 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: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 μm post-manufacturing filtered.
