Service FAQ

Frequently Asked Questions

Long-Read Sequencing is an advanced genomic sequencing technology that generates significantly longer DNA or RNA reads compared to traditional short-read sequencing methods. These long reads enable researchers to accurately resolve complex genomic regions, repetitive sequences, structural variants, haplotypes, and full-length transcript isoforms that are often difficult to characterize using short-read technologies.
Long-read sequencing has become a critical tool for genome assembly, structural variant discovery, transcriptomics, epigenomics, and precision medicine research.

Long-read sequencing offers several advantages over conventional short-read technologies, including:
Improved de novo genome assembly
Enhanced structural variant detection
Accurate haplotype phasing
Full-length transcript isoform identification
Better resolution of repetitive genomic regions
Detection of complex genomic rearrangements
Direct epigenetic modification analysis
Improved characterization of gene fusions and splice variants
These capabilities make long-read sequencing particularly valuable for complex genomic and transcriptomic studies.
