Product information
Overview
Revvity offers a line of ready to use HTRF toolbox reagents for the construction of Histone H3 methyltransferase (HMT), demethylase (HDM) and deacetylase (HDAC) activity assays. This monoclonal antibody Eu-cryptate conjugate is specific for the histone H3K36Me1 methylation mark. It can be used for the development of biochemical assays with the highest levels of specificity and sensitivity, for the screening and study of both HMTs and HDMs, such as JHDM1A.

How it works
Assay principle
Revvity’s HTRF-based reagents give researchers the flexibility to create highly specific, custom histone modification assays for enzymes such as HMTs, DMTs or HDACs. All these assays use a biotinylated histone H3 peptide substrate, a Eu-cryptate labeled detection antibody and XL665-conjugated Streptavidin. Assay specificity is derived from the combination of the chosen Eu-cryptate labeled anti-histone antibody together with the biotinylated peptide substrate. HTRF signal is proportional to the concentration of methyl-specific peptide (e.g. unmethylated, mono-, di- or tri-methylated peptide).
Assay protocol
Two step assays are performed in a single well, require no wash steps and can easily be miniaturized to a 384-well format. The enzymatic reaction containing the biotinylated peptide, enzyme, co-factors and compounds is followed by the detection step in which Eu-labeled anti-methylated histone H3 antibody and SA-XL665 are added. The HTRF signal is detected following a brief room temperature incubation, and is stable for multiple readouts.

Antibody specificity
Each Eu-cryptate labeled anti-histone antibody recognizes a single histone H3 lysine residue and methylation level. Revvity has performed cross-reactivity studies against alternative peptides and methylation levels for each antibody to ensure specificity.
