A Scalable and Sensitive Assay for HDAC Activity

Dysfunction of histone deacetylases (HDACs) is associated with many diseases including cancers, asthma and allergies, inflammatory diseases and disorders affecting the central nervous system. Because of their involvement in such a wide range of pathologies, HDACs have become a target for drug discovery. Traditional HDAC activity assays are either isotopic or fluorescent assays using artificial substrates that are prone to artifacts or fluorescence interference. There is a need for a functional assay that is sensitive, accurate and amenable to drug-screening activities.

A recent paper by Halley et al. in the Journal of Biomolecular Screening describes the evaluation of a bioluminogenic HDAC assay, the HDAC-Glo™ I/II and SIRT-Glo™ Assays. Continue reading “A Scalable and Sensitive Assay for HDAC Activity”
