We know much more about the protein and DNA content of chromatin than the RNA content. CHART was developed to answer the question of where lncRNAs localize in the genome, similar to ChIP experiments for proteins. CHART was developed while Matt was working as a Helen Hay Whitney Fellow in Bob Kingston’s lab.
