CUT&Tag and CUTAC: Simple, Fast, and Efficient Chromatin Profiling & Accessibility Mapping

CUT&Tag and CUTAC are versatile chromatin profiling strategies with unparalleled sensitivity and resolution

  • Stage: Preclinical in vitro
  • Type: Research Tool
  • Categories: Assay / Method, Nucleic Acid

Technology Overview

Cleavage Under Targets & Tagmentation ( CUT&Tag) is epigenomic profile method in which the Tn5 transposase is loaded with adaptor DNA. Tethering Tn5 to DNA-associated proteins allows concurrent cleavage and tagging of DNA adjacent to targeted chromatin elements in a single step. PCR enrichment and NGS sequences of this “Tagmented” DNA yields high-resolution genome-wide chromatin profiles. Further, the Henikoff research group has generated Cleavage Under Targeted Accessible Chromatin (CUTAC), which is a modification of CUT&Tag to produce chromatin accessibility maps by altering key parameters within the method. Used in parallel, CUT&Tag and CUTAC efficiently map chromatin profiles and the geography of open chromatin, active regulatory elements, and DNA bound transcription factors, with resolution and sensitivity that mirrors ATAC-seq and other more time intensive, complex, and laborious methods.

Applications

  • In situ genome-wide mapping of DNA-protein interactions
  • High resolution profiling of DNA regulatory elements and chromatin architecture
  • Unifying analysis of both chromatin accessibility and epigenetic landscape simultaneously
  • Single cell analysis of chromatin features, including rare cell types

Advantages

  • Simple, rapid, and cost-effective procedure done in a single tube, completed within a day
  • Multiplex-ready and compatible with low solubility complexes
  • High signal-to-noise ratio greatly reduces starting material and sequencing depth requirements
  • PCR enriched libraries easily integrate with single cell sequencing platforms on the market
  • High-throughput ready workflows for in-depth epigenetic analysis
