singlecell-dna-seqAdvances in whole-genome amplification and Novogene’s expertise have made single cell sequencing easily accessible to researchers. Novogene is one of the few NGS providers with extensive experience in single cell sequencing technology, including single-cell DNA sequencing. We offer the highest quality services in amplification, library construction, sequencing, and bioinformatics analysis to our customers, and our results have been published in leading scientific journals.

With single-cell DNA sequencing, the genomic heterogeneity of cell populations can be explored at the level of the individual cell. Genetic changes, such as point mutations and copy number variation occurring during disease and normal development processes, are profiled using the minute amounts of DNA from single cells. Applications include analysis of genetic heterogeneity within unicellular and multicellular organisms, detection of chromosomal anomalies in germ line cells, preimplantation genomic screening of embryos, and defining the genetic composition of tumors for developing more targeted therapies.

Project Example

The following studies utilized Novogene's expertise in single-cell DNA sequencing.

Single-cell exome sequencing identifies mutations in KCP, LOC440040, and LOC440563 as drivers in renal cell carcinoma stem cells
Cell Research 1-4 (2016)

Renal cell carcinoma (RCC), the most common form of adult kidney cancer, has a low mutation rate. In this study, three novel renal cancer stem cell driver mutations were discovered using Novogene’s advanced single-cell exome sequencing technology. With over 140X coverage, 297 somatic SNVs were found, with 141 of these located in coding regions. Three missense mutations in the loci KCP, LOC440563, and LOC440040 were unique to CD133+ RCC cells and have not been reported in RCC before. This study suggests that these three novel mutations could play significant roles in RCC diagnostics and therapeutic treatment.

Probing meiotic recombination and aneuploidy of single sperm cells by whole-genome sequencing.
Science, 338:1627-1630 (2012)

In this study, Novogene’s single-cell DNA sequencing technology was used to analyze the genomes of individual human sperm following amplification by MALBAC. The results revealed variation in the distribution of recombination events along the genome and provided new insights into meiotic mechanisms.
