Mammalian Micro-C-XL.

Chromosome Conformation Capture (3C) methods are a family of sequencing-based assays to measure the three-dimensional structure of genomes, with Hi-C as the most prominent method in widespread use. The Micro-C-XL protocol is technical variant that improves the resolution and signal-to-noise ratio of the Hi-C protocol and therefore offers enhanced detection of chromatin features such as chromosome loops and fine-grained resolution of topologically associated domains. Here we describe a detailed step-by-step protocol for Micro-C-XL in mammalian cells.
