Asymmetrical NG/NG-dimethyl arginine
This antibody will be of central importance in analysing the methylation status of chromatin and transcription factors. Since it recognises both dimethyl and monomethyl arginine it can be used in parallel with ab413 (detects dimethyl arginine only) and ab414 (detects monomethyl arginine only) to monitor the exact modification status. A tissue culture supernatant version is available as ab5394.
Our Abpromise guarantee covers the use of ab412 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.|
|ChIP||Use 3µl for 106 cells.|
|ELISA||Use a concentration of 0.05 - 0.5 µg/ml.|
Sonicated Chromatin prepared from untreated or 17beta-estradiol (E2) treated MCF7 cells was subjected to the ChIP procedure (see protocol) with ab412 to mono and dimethyl Arginine.
Immunoprecipitated chromatin was analysed in the proximal region of the estrogen-responsive pS2 promoter (as shown above) and quantified by real-time PCR (values are % of inputs). The primers are designed to follow the nucleosome E (including the Estrogen Responsive Element ERE). 3
