产品概述

Host Species: Mouse
Clonality: monoclonal
Isotype: IgG1
Background:
Histone methylation and demethylation is dynamically regulated by respectively histone methyl transferases and histone demethylases. Levels of H3K27 dimethylation are higher in silent genes than in active genes suggesting that this histone modification is associated with transcriptional repression. Trimethylation of histone H3 on lysine 27 (H3K27me3) is a repressive posttranslational modification mediated by the histone methyltransferase EZH2.
Description:
Monoclonal antibody raised in mouse against histone H3, di– or trimethylated at lysine 27 (H3K27me2/3), using a KLH–conjugated synthetic peptide
Assay Conditions:

Cross reactivity of the monoclonal antibody directed against H3K27me2/3
Dot Blot analysis was performed to test the cross reactivity of the monoclonal antibody against H3K27me2/3 (cat. # 25242) with peptides containing other modifications of histone H3. Other modifications include mono-methylation of lysine 27 and mono-, di- and trimethylation of lysines 9 and 36. One hundred to 0.2 pmol of the peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:300.

Western blot analysis using the monoclonal antibody against H3K27me2/3
Histone extracts from HeLa cells (HeLa HE, 20 μg) were analysed by Western blot using the monoclonal antibody against H3K27me2/3 (cat. # 25242) diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the right.
