Anti-dimethyl-Histone H3 (Lys79), clone

Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the 'beads on a string' structure. Applications: Suitable for use in Western Blot, Dot Blot and Histone-Peptide assay. Chromatin Immunoprecipitation (ChIP) has been reported by an independent laboratory. Other applications not tested. Recommended Dilution: Western Blot: 1:4000 Recombinant Histone H3 or acid extracted HeLa cell proteins were resolved by electrophoresis, transferred to nitrocellulose and probed with H5110-14R1. Proteins were visualized using an IgG (HRP) goat anti-rabbit and a chemiluminescence detection system., Peptide Dot Blot Analysis: 1:2500 dilution of this lot detected the immunizing peptide containing dimethyl-lysine 79. Some crossreactivity with peptide containing monomethyl-lysine 79 was also seen. No crossreactivity to other related histone peptides was found. The antibody did not recognize a histone peptide containing the dual modification of dimethyl-lysine 79 and phospho-threonine 80., Histone-Peptide Specificity Analysis: 1:25-1:1600 dilution of this lot were incubated with histone H3 peptides containing various modifications conjugated to Luminex(R) microspheres. Peptide containing dimethyl-lysine 79 was readily detected. Some crossreactivity with peptide containing monomethyl-lysine 79 was seen. The antibody did not detect a histone H3 peptide containing the dual modification of dimethyl-lysine 79 and phosphothreonine 80., Optimal dilutions to be determined by the researcher.
