Our Abpromise guarantee covers the use of ab49126 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ChIP Use at an assay dependent concentration.
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay was 1:312500.

WB Use a concentration of 1.25 µg/ml. Detects a band of approximately 43 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Relevance
    The protein encoded by this gene is a member of the SWI/SNF family of proteins. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. Two transcript variants encoding different isoforms have been found for this gene.

Thank you for your enquiry. I can confirm that the blocking solution is 5% skimmed milk in PBS. The antibody diluent is also 5% skimmed milk. Lastly, the incubation condition is 2 hours at 37℃. Of course, overnight at 4℃ is also ok for blotting. ...
