Purpose of the Study:
- To provide a detailed protocol for the Cleavage Under Targets and Tagmentation (CUT&Tag) technique.
- To enable accurate identification of histone modifications in immune cells.
- To overcome challenges associated with conventional epigenetic profiling methods.
Main Methods:
- Detailed protocol for the CUT&Tag chromatin profiling technique.
- Application of CUT&Tag for identifying histone modifications.
- Method validated in human and mouse lymphocytes.
Main Results:
- Successful implementation of the CUT&Tag protocol for histone modification profiling.
- Demonstrated utility of CUT&Tag in lymphocytes.
- Provided a robust method for epigenetic analysis in immune cells.
Conclusions:
- The CUT&Tag technique offers a powerful approach for studying epigenetic regulation in immune cells.
- This protocol facilitates a deeper understanding of gene regulation by identifying histone modifications.
- The method addresses existing technical challenges in chromatin profiling.
