SensoLyte® 520 HDAC Assay Kit – Ultra-sensitive

Current HDAC assay kit has been based on a short wavelength substrate whose detection is darkened by the presence of autofluorescence interference. SensoLyte® has ushered in the dawn of ultra-sensitivity.

AnaSpec, EGT Group's SensoLyte® 520 HDAC Activity Assay Kit is the industry's longest wavelength assay kit for HDAC detection (Ex/Em = 490 nm/520 nm). With a longer wavelength, the SensoLyte®520 HDAC Activity Assay Kit avoids the autofluorescence interference from cell components and test compounds that is commonly found in traditional HDAC assay kits.

Histone deacetylase (HDAC) enzymes modulate gene expression through the deacetylation of lysine residues on histone proteins and act as transcriptional repressors of genes. Based on their role in cell cycling, apoptosis and differentiation, HDACs have been chosen as therapeutic targets for the treatment of cancer and neurodegenerative diseases.

The SensoLyte® 520 HDAC Activity Assay Kit provides a convenient, two-step homogeneous procedure for measuring HDAC activity using a cell-permeable fluorogenic substrate. Without a time-consuming cell extraction step, this assay can be used to measure HDAC activity directly in cell culture in a 96-well plate. This kit can also be used for high throughput screening of HDAC inhibitors using extracts or purified enzymes.

The kit contains: • HDAC 520 substrate • Deacetylated reference standard for calibration • HeLa nuclear extract • Assay buffer • Cell lysis buffer • HDAC developer • Trichostatin A (HDAC inhibitor)
