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.
Storage
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.
For a carrier free (BSA and azide free) version of this product see product #49077.
Specificity / Sensitivity
Rabbit (DA1E) Monoclonal Antibody IgG Isotype Control is not directed against any known antigen. This antibody functions as an isotype control for rabbit IgG antibodies.
Background
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.
