Flow cytometric analysis of unpermeabilized HeLa cells using CD44 (156-3C11) Mouse mAb #3570 (solid line) compared to concentration-matched Mouse (E5Y6Q) mAb IgG2a Isotype Control (dashed line). Anti-mouse IgG (H+L) F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4408 was used as a secondary antibody.
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 mouse embryonic fibroblasts treated with tunicamycin (2ug/ml, 10hr) and either Mouse (E5Y6Q) mAb IgG2a Isotype Control, Normal Rabbit IgG #2729, or CHOP (L63F7) Mouse mAb #2895 using SimpleChIP® Plus Enzymatic Chromatin IP Kit (Magnetic Beads) #9005. The enriched DNA was quantified by real-time PCR using SimpleChIP® Mouse ATF-3 Intron 1 Primers #13059, mouse CHOP promoter primers, and SimpleChIP® Mouse RPL30 Intron 2 Primers #7015. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

Product Usage Information

Important! This control antibody must be diluted to the same concentration (not dilution) as the specific antibody used in analysis. Higher background fluorescence may result if excessive amounts of isotype control are used. For protocol details, please reference the product page for the specific antibody used in analysis.


Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

Mouse (E5Y6Q) mAb IgG2a Isotype Control is not directed against any known antigen. It functions as an isotype control for mouse IgG2a 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.
