Flow cytometric analysis of live mouse splenocytes using CD45 (30-F11) Rat mAb (APC Conjugate) #41104 (solid line) compared to concentration-matched Rat (LTF-2) mAb IgG2b Isotype Control (APC Conjugate) (dashed line).
This Cell Signaling Technology antibody is conjugated to APC under optimal conditions and tested in-house for direct flow cytometric analysis in mouse cells.
Note: This control antibody must be diluted to the same concentration (not dilution) as the specific antibody in analysis. See Directions on Use.
Directions 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 rat IgG isotype control are used.
Supplied in 10 mM NaH2PO4, 150 mM NaCl, 0.09% NaN3, 0.1% gelatin, pH 7.2. 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 rat 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.
