Our Abpromise guarantee covers the use of ab211488 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IP||Use at an assay dependent concentration.
0.2 µg coated onto 50 µL Dynabeads® sheep-anti-rabbit IgG.
|ELISA||Use a concentration of 0.005 - 4 µg/ml.|

- m22G antibody
The IP was performed in a U-bottom non-adsorbing propylene 96-well plate.
ab211488 (0.2 μg) was coated into Dynabeads® sheep-anti-rabbit IgG (50 μl) for 1h at RT.
Unmodified/modified oligonucleotides (5 μM) were added to samples containing the antibody/bead complexes and incubated with agitation for 1 hour at RT.
After washing, Peroxidase-conjugated Streptavidin was incubated at 1/1000 dilution with agitation for 1 hour at RT.
ECL substrate was then added and the results read in a non-transparent 96-well plate with a digital detector and analyzed using ImageJ.

BSA-conjugated m2,2G (modified) and G (unmodified) nucleosides were coated onto wells of a 96 well plate. ELISA was performed on 1.0 µg/ml of antigen using ab211488 at a concentration range of 0.005-4.000 µg/ml, followed by Goat Anti-Rabbit IgG, (H+L), alkaline phosphatase conjugated secondary antibody at 1/2500 dilution.
