For more than a decade, scientists studying epigenetics have used a powerful method called ChIP-seq to map changes in proteins and other critical regulatory factors across the genome. While ChIP-seq provides invaluable insights into the underpinnings of health and disease, it also faces a frustrating challenge: its results are often viewed as qualitative rather than quantitative, making interpretation difficult.

But, it turns out, ChIP-seq may have been quantitative all along, according to a recent report selected as an Editors’ Pick by and featured on the cover of the Journal of Biological Chemistry.

“ChIP-seq is the backbone of epigenetics research. Our findings challenge the belief that additional steps are required to make it quantitative,” said Brad Dickson, Ph.D., a staff scientist at Van Andel Institute and the study’s corresponding author. “Our new approach provides a way to quantify results, thereby making ChIP-seq more precise, while leaving
