Histone H3K27me1 Antibody Description: Rabbit polyclonal antibody recognizing the histone H3 monomethylated at lysine 27. Histone H3 is one of the four proteins that are present in the nucleosome, the basic repeating unit subunit of chromatin, consisting of 147 base pairs of DNA wrapped around an octamer of core histone proteins (H2A, H2B, H3 and H4). Methylation of lysine 27 is associated with transcriptional repression by the Polycomb complex of proteins and the formation of facultative heterochromatin.
 
Histone H3K27me1 Antibody Immunogen: Synthetic peptide derived from human histone H3 monomethylated at lysine 27.

Histone H3K27me1 Antibody Formulation: Affinity-purified IgG (1 mg/ml) in PBS, pH 7.3, with 0.02% sodium azide and 50% glycerol.

Histone H3K27me1 Antibody Quality Control: This antibody has been validated for use in IF, IHC and Western blot. It has also been validated for specificity by dot blot and histone peptide array and it has been confirmed that this antibody:
  • Is specific for H3K27me1
  • Has no cross-reactivity to related modifications
  • Is unaffected by nearby modifications

Histone H3K27me1 Antibody Storage and Stability: Stable for 2 years at -20°C from date of receipt.

13-0015 SNAP-ChIP Data

SNAP-ChIP Data: Histone H3K27me1 antibody (1:60 dilution) was tested in a native ChIP experiment with chromatin from HEK-293 cells (~1x10^6 cells). Specificity (left Y-axis) was determined by qPCR for the duplicate DNA barcodes corresponding to each modified nucleosome in the SNAP-ChIP K-MetStat panel (EpiCypher Catalog No. 19-1001, X-axis). Black bar represents antibody efficiency (right Y-axis; log scale) and indicates percentage of the barcoded H3K27me1 nucleosome target immunoprecipitated relative to Input. The antibody exhibited good specificity for the target (<10% cross-reactivity outside H3K27me1) and high efficiency (18.1%). Error bars represent mean ± SEM from two barcoded nucleosome replicates in a single ChIP experiment.
