Multi-CUT&Tag to simultaneously profile multiple chromatin factors

STAR Protoc. 2022 Jan 20;3(1):101100. doi: 10.1016/j.xpro.2021.101100. eCollection 2022 Mar 18.

Abstract

Genome-wide chromatin mapping approaches typically focus on one protein at a time. We recently developed multi-CUT&Tag, which enables simultaneous mapping of multiple chromatin proteins in the same single cells or pools of cells. Using barcoded adapters loaded onto antibody-protein A-Tn5 transposase complexes, multi-CUT&Tag marks the locations of each chromatin protein and directly detects colocalization of different proteins in the same cell(s). Although slightly more laborious than CUT&Tag, multi-CUT&Tag provides a powerful option for generating multi-factor maps for epigenomic profiling. For complete details on the use and execution of this protocol, please refer to Gopalan et al. (2021).
