Clone Host Grade Applications
Monoclonal Rabbit Supernatant B IP
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.
Catalog #H5110-14R1
ApplicationsSuitable 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 DilutionWestern 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® 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.

PuritySupernatant
ImmunogenSynthetic peptide ccorresponding to the sequence (...DFme2KTD...), where me2K corresponds to dimethyl-lysine at position 79 of histone H3 conjugated to KLH. The immunizing sequence is identical in human, mouse, rat and yeast.
SpecificityRecognizes human dimethyl-histone H3 (Lys79) at ~17kD.
Broad species crossreactivity is expected based on sequence conservation.
