Anti-Histone H3 (aDi-Methyl R17) Antibody

Raised in rabbit and affinity-purified for high-stringency epigenetic studies, this polyclonal antibody from Antibodies.com selectively recognises histone H3 only when arginine 17 is asymmetrically di-methylated (H3R17me2a). The reagent is supplied at 50 µl per vial at a working concentration of 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, and is validated for Western blot, immunohistochemistry, immunofluorescence and immunoprecipitation across human, mouse and rat samples. SDS-PAGE analysis confirms >95% purity after affinity chromatography using an epitope-specific immunogen, and the unconjugated IgG format allows flexible pairing with secondary reagents in chromatin and transcription research. The expected molecular weight of the target is approximately 15 kDa (observed ~17 kDa), consistent with modified histone H3.1/H3.2 species carrying the asymmetric di-methyl mark at Arg17. The Antibodies.com product ships refrigerated and is intended for research use only, complementing the corresponding mono-methyl and symmetric di-methyl R17 reagents in the same catalogue range.
