Researchers from the University of Illinois have created a process for the epigenomic analysis of single cells. This process combines the uses of single cell microfluidics and chromatin immunoprecipitation (ChIP) for the analysis of DNA modifications in single cells.This technology has the potential to greatly decrease the number of cells needed from a biopsy to test for different cancers. It may also allow the study of traveling cell cancers that are only present in very small almost undetectable quantities.
