One such method, known as DNAse-ChIP, was used to map open chromatin regions using an indirect approach where unbound DNA was cleaved by DNaseI and ligated to a biotinylated linker [13], [14], [15].
We tested this possibility by using chromatin immunoprecipitation.
The mitotic phases are well discernible by using chromatin staining.

In these studies, enhancers have been identified using methods that detect open chromatin, specific histone modifications, and enhancer RNAs (eRNAs).
The system could also be improved by using bacterial artificial chromosomes (BAC) as open chromatin and copy number-dependent expression vehicles (Blaas et al. 2009) in combination with serial, accumulative RMCE reactions for introduction of multiple gene copies with various available heterospecific FRT sites into the same genomic locus.
Chromatin analysis reveals that H3mm7 facilitates transcription by forming an open chromatin structure around promoter regions including those of myogenic genes.
Histologically, the lymphoblasts were characterized by open chromatin, numerous nucleoli and vacuolization of the cytoplasm (Supplementary Figure 1).
We performed overlap analysis between conserved genomic regions (as determined by BLSSpeller) and open chromatin regions (see Supplementary Methods 1.2).
