Hi-C sequencing


Hi-C is a technique derived from the Chromosome Conformation Capture(3C) combined with high-throughput sequencing. It mainly crosslinks DNA fragments that are adjacent in space structure, then enriches the crosslinked DNA fragments, performs high-throughput sequencing, futher more combines with bioinformatics analysis methods to achieve capture of interactions between chromosome segments throughput the genome.

Application Areas

Genome Assembly

Hi-C Interaction

Hi-C data were used to assemble the jumbled genome sequences to the chromosomal level

Hi-C combining with RNA-seq , resequencing, ATAC-seq, Chip-seq, WGBS and other research methods could be used to conduct multi-omics analysis, and further in-depth study biological 

Hi-C Advantages

●Rich experience
Completed nearly 300 species and built nearly a thousand libraries.
●Accurate service
Provided customized services for specific species.
●Patent protection
Acquired patents and software copyrights for experimental and bioinformatics analysis.
●Remarkable achievement
Accomplished the assembly of polyploidy species by Hi-C technology, and up to 100% of the genome is anchored onto the chromosome.

Genome Assembly


Based on the draft genome assembled from the second or third generation sequencing and the number of known chromosomes. The Hi-C sequencing data was used to divide the sequences of the draft genome into chromosomes, and then the order and direction of each sequence on the chromosome was determined to obtain the genome at the chromosome level.

Advantages and Application Areas

●Material availability
There is no need to construct a genetic population, and only one material can achieve chromosome localization.
●Wild applicability
It is applicable not only to simple genome, but also to complex with polyploidy, high heterozygosity and high repetition.
●High accuracy
The use of heat maps can accurately and intuitively detect assembly errors and correct them.
●High coverage
The high marker density can anchored more contig onto chromosome.


High-resolution chromatin three-dimensional structure information can be obtained through studying genome-wide interaction information by high-throughput sequencing technology  assist with bioinformatics analysis methods .Hi-C combining with RNA-seq , resequencing, ATAC-seq, Chip-seq, WGBS and other research methods could be used to conduct multi-omics analysis, and further in-depth study biological problems from various aspects.
