Institute of Biomedicine of Seville (IBiS), University Hospital Virgen del Rocío, 2Institute of Biochemistry, Medical Faculty, Friedrichstrasse 24, Member of the German Center for Lung Research, Justus-Liebig-University The plasticity of nuclear architecture is controlled by dynamic epigenetic mechanisms including non-coding RNAs, DNA methylation, nucleosome repositioning as well as histone composition and modification. Here we describe a Formaldehyde-Assisted Isolation of Regulatory Elements (FAIRE) protocol which allows the determination of chromatin accessibility in a reproducible, inexpensive, and straightforward manner. Medicine Isolation and Cultivation of Adult Rat Cardiomyocytes Franziska Nippert1, Rolf Schreckenberg1, Klaus-Dieter Schlüter1 1Institute of Physiology, Justus Liebig University Giessen Here, we present a protocol for the isolation and cultivation of adult rat ventricular cardiomyocytes (ARVC). Isolated ARVC can be used for short and long-term cultivation. The isolation and cultivation of ARVC can play a key role in developing new treatment regimens for cardiac diseases. Genetics Chromatin Immunoprecipitation (ChIP) in Mouse T-cell Lines Benedetto Daniele Giaimo1, Francesca Ferrante1, Tilman Borggrefe1 1Institute of Biochemistry, University of Giessen This work describes a protocol for chromatin immunoprecipitation (ChIP) using a mature mouse T-cell line. This protocol is suitable to investigate the distribution of specific histone marks at specific promoter sites or genome-wide.
