Highly quantitative measurement of differential protein-genome binding with PerCell chromatin sequencing

Area of Science:

• Genomics
• Epigenetics
• Molecular Biology

Background:

• Standardized chromatin sequencing methods are lacking, hindering data analysis and sharing.
• Quantitative comparisons across experimental conditions are challenging with current techniques.

Purpose of the Study:

• To introduce a universal, low-cost strategy for 2D chromatin sequencing.
• To provide researchers with tools for analyzing protein-genome binding data.
• To facilitate quantitative comparisons and data sharing across laboratories.

Main Methods:

• Development of the PerCell ChIP-seq methodology for wetlab and drylab applications.
• Utilizing defined cellular ratios with orthologous species' chromatin for normalization.
• Implementation of internal normalization for quantitative accuracy.

Main Results:

• A flexible and virtually no-cost chromatin sequencing methodology is established.
• Enables rapid, quantitative, and internally normalized chromatin sequencing.
• Demonstrated utility in in vivo zebrafish and cancer cell epigenomics.

Conclusions:

• The PerCell ChIP-seq strategy offers a universal solution for chromatin sequencing.
• Facilitates cross-species comparative epigenomics and robust data analysis.
• Broad applicability across various research disciplines and experimental designs.
