In-Nucleus Hi-C in Drosophila Cells

Overview

The nucleus Hi-C protocol enables the exploration of chromosomal conformation, allowing for the characterization of chromatin loops, domains, and compartments within the genome. This method provides high-resolution profiling of genomic interactions, yielding consistent coverage across various genomic distances.
