Histone deacetylase & acetylase screening

Cambridge Bioscience offers a fully defined, flexible profiling and screening service for potential drug inhibitors of HDACs/HATs. Using specific substrates in either radioisotope-based or fluorogenic-based functional assays, these highly sensitive and highly reproducible assays provide minimal false positives and negatives. These features make this service ideal for ensuring the right drug candidates are selected and progressed through the pipeline. Testing from regular profiling to miniaturised HTS platform is also available.

Benefits of using the HDAC and HAT screening and profiling service
• Gold standard radioisotope-based assay service for HATs or fluorogenic peptide substrate assay for HDACs
• Flexible - available for profiling and low cost high-throughput screening
• High sensitivity
• High reproducibility
• No antibody requirement
• Minimum false positives and negatives
• No intermediate dilution
• Small compound requirement - only nanolitres of compound required

HDAC and HAT services available
