Protocol for High-Throughput Analysis of Sister-Chromatids Contacts.

Sister chromatid interactions are a key step to ensure the successful segregation of sister chromatids after replication. Our knowledge about this phenomenon is mostly based on microscopy approaches, which have some constraints such as resolution limit and the impossibility of studying several genomic positions at the same time. Here, we present a protocol for Hi-SC2, a high-throughput sequencing-based method, to monitor sister chromatid contacts after replication at high resolution throughout the genome, which we applied to study cohesion in . For complete details on the use and execution of this protocol, please refer to Espinosa et al. (2020).
