This antibody gave a positive result in ELISA against the immunizing peptide ab27898 (dark blue line). It gave a negative result in ELISA against the non-modified equivalent peptide ab27899 (pink line). This antibody also gave a negative result in ELISA against PSD95 peptide - phospho T19 ab17166 (yellow line), Histone H3 peptide - tri methyl K9 ab1773 (blue line), Histone H3 peptide - tri methyl K36 ab1785 (purple line), Histone H3 peptide- tri methyl K37 ab24417 (brown line) and Histone H3 peptide ab26308 (green line). This indicates that it is specific for the modified peptide.
