Hi-C technology is derived from the technology of Chromosome Conformation Capture-3C, takes the entire nucleus as the research object, adopts high-throughput sequencing technology, and combines bioinformatics methods to study the spatial relationship of the entire chromatin DNA in the whole genome, obtain high-resolution three-dimensional structure information of chromatin by capturing all DNA interaction patterns inside, and analyze it with ATAC-seq, ChIP-seq, genome, transcriptome data, etc., thereby elucidating the related mechanism of organism trait formation from gene regulatory network and epigenetic network.

Requirements
Total amount of DNA for initial database construction of a single librarythe total is 10 μg.
- Sample delivery requirements for individual libraries (insitu Hi-C)
Requirements for plant samples
On fresh living plants, it is recommended to take relatively young leaves, root hairs, and other parts for sufficient cross-linking; When genomes such as wheat are more complex, fresh tender leaves are required for sample submission.
Requirements for tumor samples
Species: suspended cells, adherent cells, fresh tissues
