Synthetic peptide conjugated to KLH derived from within residues 1 - 100 of Human Histone H3 di methylated at K4.
(Peptide available as ab7768.)
Our Abpromise guarantee covers the use of ab11946 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-P||Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
|ChIP||Use 2-4 µg for 25 µg of chromatin.|
|ICC/IF||1/500. Use with paraformaldehyde or with methanol fixed cells.|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 17 kDa (predicted molecular weight: 15 kDa).Can be blocked with Histone H3 (di methyl K4) peptide (ab7768).|
Chromatin was prepared from Hela cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10min. The ChIP was performed with 25µg of chromatin, 2µg of ab11946 (blue), and 20µl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach). Primers and probes are located in the first kb of the transcribed region.
