Histone Post-translational Modifications
Innovative screening assays for detecting PTM

Leading Innovation in Post-Translational Modification Detection
For over a decade, the FLUOR DE LYS® deacetylase assay platform has revolutionized assessment of HDAC & Sirtuin enzyme activity, freeing researchers from cumbersome protocols required with radiolabeled or other modified histone-based methods. Our high-quality assays utilize patented substrate/developer chemistry in combination with high-activity, high-purity enzymes, to deliver more high-quality hits. Broad-class HDAC/Sirtuin screening assays are available in chemiluminescent, fluorescent, and colorimetric formats, and backed by a panel of epigenetic modulators and PTM-specific antibodies.
Active Enzymes & Drug Discovery Assays
FLUOR DE LYS® HDAC & Sirtuin Assays
Convenient Screening Formats from the Pioneer in Non-Radioactive Assays
- Non-radioactive, homogeneous, HTS compatible formats
- Green & chemiluminescent assays available to minimize interference
- Assay all HDAC classes from multiple sources
- High-activity, in-house manufactured control enzymes
- Widely cited in peer-reviewed literature
Transferase & Demethylase Assays
Quantify Acetyltransferase & Methyltransferase Activity
Our acetyltransferase and methyltransferase activity kits are homogeneous mix-and-read fluorescent assays for the determination of any acetyl-CoA dependent acetyltransferase activity or any S-adenosyl-L-methionine dependent methyltransferase activity, respectively. They are high throughput amenable and suitable for end-point or kinetic assay protocols.
Screen LSD1 Inhibitors
LSD 1 was the first enzyme identified to actively demethylate lysine residues, and holds promise as a therapeutic target for a number of cancers. The LSD1 Fluorometric Drug Discovery Kit provides human recombinant LSD1 and all reagents for measuring its activity in a sensitive, real-time fluorescent assay.
