Amplification-Free ChIP-Seq
Chromatin Profiling by Directly Sequencing Small Quantities of Immunoprecipitated DNA
Chromatin structure and transcription factor localization can be assayed genome-wide by sequencing genomic DNA fractionated by protein occupancy or other properties. However, current technologies involve multiple steps that introduce bias and inefficiency. Here we apply a single-molecule approach to directly sequence chromatin immunoprecipitated DNA with minimal sample manipulation. This method is accurate, compatible with just 50 picograms of DNA and should thus facilitate charting chromatin maps from limited cell populations.
