Flow cytometric analysis of live human peripheral blood mononuclear cells using CD19 (SJ25C1) Mouse mAb (PerCP Conjugate) #47432 (right) and co-stained with CD3-APC, compared to concentration-matched Mouse (MOPC-21) mAb IgG1 Isotype Control (PerCP Conjugate) (left).
This Cell Signaling Technology antibody is conjugated to PerCP under optimal conditions and tested in-house for direct flow cytometric analysis in human cells.
Note: This control antibody must be diluted to the same concentration (not dilution) as the specific antibody in analysis. See Directions on Use.
Important for Use: Important: Dilute this control antibody to the same concentration (not dilution) as specific antibody in analysis. Higher background fluorescence may result if excessive amounts of mouse IgG isotype control are used. Do not use this antibody at 1:50 or 1:20 dilution like other CST PerCP conjugated antibodies.
Supplied in 10 mM NaH2PO4, 150 mM NaCl, 0.09% NaN3, 0.1% gelatin, pH7.2. This product is stable for 6 months when stored at 4ºC. Do not aliquot the antibody. Protect from light. Do not freeze.
The antibody is not directed against any known antigen. It functions as an isotype control for mouse monoclonal antibodies.
Isotype control antibodies are used to estimate the nonspecific binding of target primary antibodies due to Fc receptor binding or other protein-protein interactions. An isotype control antibody should have the same immunoglobulin type and be used at the same concentration as the test antibody.
