Histone turnover
WebbThe Histone Demethylase Activity kit is to quantitatively measure the enzymatic activity of formaldehyde-producing enzymes such as histone demethylases. The kit is unique in that the product of these enzymatic demethylation reactions, formaldehyde, is quantitated directly by a fluorescent product. No separation or washing is required. Histones containing transcriptionally active marks have been consistently found to have faster turnover rates than histones containing silent marks. Interestingly, the presence of both active and silent marks on the same peptide resulted in a slower turnover rate than either mark alone on that same peptide. Visa mer HeLa S3 were maintained between 5-10 × 105 cells/ml throughout the experiment and, before the time course, were grown in minimum essential Joklik modified media (Sigma Aldrich, St. … Visa mer Cell pellets were thawed on ice before nuclei isolation and histone extractions as previously described [47].

A hexasome wraps ~100–110 bp of DNA with an H2A:H2B dimer asymmetrically detached at the entry or exit site [ 10 ].
