Acetyl Histone H3-K23 Quantification Kit (Colorimetric) is use for measuring acetylation of histone H3-K23.
Acetylation of histones including histone H3 has been involved in the regulation of chromatin structure and recruitment of transcription factors to the gene promoters. Histone acetyltransfeases (HAT) and histone deacetylases (HDACs) play a critical role in control of histone H3 acetylation at multiple sites. Histone H3 at lysine 23 (H3-K23), along with K9, K14 and K18 are primary acetylated sites of histone H3. Acetylation of histone H3-K23 is tightly involved in the cell cycle regulation, cell proliferation and apoptosis. Acetylation of histone H3-K23 is also correlated with transcription activation. An imbalance in the equilibrium of histone H3 acetylation including K23 acetylation has been associated with tumorigenesis and cancer progression. Histone H3-K23 acetylation may be increased by inhibition of HDACs and decreased by HAT inhibition. Thus quantitative detection of acetyl histone H3-K23 would provide useful information for better understanding epigenetic regulation of gene activation and for developing HAT or HDAC-targeted drugs. The Acetyl Histone H3-K23 Quantification Kit (Colorimetric) provides a tool for measuring acetylation of histone H3-K23.
For specifically measuring histone H3-K23 acetylation using a variety of mammalian cells (human, mouse, etc.) including fresh and frozen tissues, cultured adherent and suspension cells.

Upon receipt, store C3 and Standard control at –20°C. Store all other components at 4°C away from light. The components of the kit should be stable for 6 months when stored properly.Note: Check if buffers C1 and C2 contain salt precipitates before using. If so, warm (at room temperature or 37°C) and shake the buffers until the salts are redissolved.
