Product Overview

The EpiQuik™ HDAC4 Assay Kit (Colorimetric) is a complete set of optimized buffers and reagents to colorimetrically measure the total amount of HDAC4 proteins quantitatively, through an ELISA-like method, from fresh tissue and cultured cells of human and mouse without the need for electrophoresis and transfer processes.

  • Very fast procedure, which can be finished within 4 hours.
  • Innovative colorimetric assay to quantitatively measure HDAC4 protein amount without the need for electrophoresis. 
  • High sensitivity and specificity -- HDAC4-specific detection with a detection limit as low as 1 ng of HDAC4 protein.
  • Strip microplate format makes the assay flexible: manual or high throughput analysis.
  • HDAC4 control is included, which allows for the HDAC4 protein amount of the sample to be properly quantified.
  • Simple, reliable, and consistent assay conditions.

Background Information
Histone deacetylases (HDACs) play a critical role in transcriptional repression of gene expression in eukaryotic cells by catalyzing the hydrolytic removal of acetyl groups from histone lysine residues. HDACs are tightly involved in cell cycle regulation, cell proliferation, and the development of human cancer. HDAC inhibition displays significant effects on apoptosis, cell cycle arrest, and differentiation in cancer cells. HDAC inhibitors are currently being developed as potential anti-cancer agents. Three distinct families of HDACs have been described, comprising a group of at least 20 proteins in humans. HDAC4 is a class II histone deacetylase containing 1084 amino acid residues. HDAC4 possesses histone deacetylase activity and represses transcription when tethered to a promoter. This protein does not bind DNA directly, but through transcription factors MEF2C and MEF2D. It seems to interact in a multiprotein complex with RbAp48 and HDAC3. Also, through interaction with many transcription factors, HDAC4 regulates many biological processes including cell cycle progression. HDAC4 promotes cancer growth and is overexpressed in many different cancer types such as colon cancer and breast cancer. 

Principle & Procedure
In an assay with this kit, the unique HDAC affinity substrate is stably coated on the strip well. The sample is added into the well and HDAC4 proteins contained in the sample bind to the substrate. The bound HDAC4 can be recognized with an HDAC4-specific antibody and colorimetrically quantified through an ELISA-like reaction. After reading the optical density on a microplate spectrophotometer at a wavelength of 450 nm, the amount of HDAC4 will be proportional to the intensity of the color development.
