Indirect ELISA and competitive ELISA results show that this antibody is specific to m6A. Indirect ELISA was performed by coating BSA conjugated m6A at 20ng/well followed by blocking with 1% BSA. Serial diluted primary antibody was added to the plates and incubated at 37℃. HRP-goat anti-mouse was used for detection. Competitive ELISA was performed similarly except that different concentration of m6A or its structure analogue compounds are mixed in primary antibody (fixed at 0.05μg/mL).

Total RNA was isolated from HEK-293 cell line and was dotted to NC membrane at different amount as indicated above the dots. The membrane was blocked with BSA and blotted with m6A antibody 68055-1-Ig at 1:2000 followed by incubation of HRP-goat anti-mouse secondary antibody. Signal was developed by ECL substrate. A parallel dot blot was performed using unrelated antibody with the same isotype (UCP2 antibody 66700-1-Ig) at the same dose.
