CD19, APC, clone: MB19-1, eBioscience™

Description

Description: The MB19-1 monoclonal antibody reacts with mouse CD19, a 95kDa transmembrane glycoprotein. CD19 is expressed by B cells during all stages of development excluding the terminally differentiated plasma cells. Follicular dendritic cells also express CD19. Together CD21, CD81, MHC class II, and CD19 form a multimolecular complex that associates with the BCR. Signaling through CD19 induces tyrosine phosphorylation, calcium flux and proliferation of B cells. Staining of B cells with MB19-1 and its conjugates is usually dimmer than the rat anti-mouse CD19 antibody, clone 6D5.Applications Reported: The MB19-1 antibody has been reported for use in flow cytometric analysis.Applications Tested: The MB19-1 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.5 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: 0.2μm post-manufacturing filtered.
