The generation of high-quality genome assemblies is critical for their own comprehensive characterization and use as reliable reference sequences. Long-read sequencing is capable of generating long-read and ultra-long sequencing read lengths that span complex genomic regions, providing a more complete and structurally accurate genome. CD Genomics is a leading global life sciences company, and we are continually expanding our solutions and improving our available resources to help scientists accelerate their basic research. Based on our advanced PacBio SMRT sequencing and ONT Nanopore sequencing, and years of sequencing experience, we are committed to providing the best solutions to meet the project needs of our customers worldwide.
Genome assembly is the process of combining your reads (short reads, long reads, or both) into long contiguous sequences (overlapping clusters). High-quality genome chromosome-scale sequences provide an important foundation for downstream analysis in genomics, especially haplotype resolution and construction of complete genomes, and play a key role in genome annotation, mutation detection, evolutionary analysis, gene function studies, comparative genomics, and more. Many different methods and tools exist to assemble genomes. However, genome assembly with short-read sequencing data is computationally demanding and often results in fragmented assemblies due to lack of sequence overlap. Accurate assembly of large structural variants, repetitive sequences, and GC-rich regions using short-read sequencing technologies is extremely challenging. The advent of long-read sequencing technologies has greatly improved the integrity of complex genome assemblies.
