CD Genomics provides comprehensive whole genome amplification to discover of DNA mutations in single cells.

The Introduction of Single-Cell DNA Sequencing

Random, low-abundance mutations in the genome of somatic cells are difficult to be qualified and characterized. To circumvent this problem and simultaneously account for the mutational heterogeneity within tissues, sequencing of a representative number of single cells is applied.

Whole genome amplification (WGA) technology has emerged as a tool to perform assessment DNA mutations in single, or a limited number of cells. To enable the discovery of true variation in single cells, the WGA of single-copy genomic DNA starting from a single cell is optimized to obtain sufficient amounts of DNA for sequencing. Faced with the problem of limited or insufficient DNA quantity for various downstream analysis, amplified DNA can be directly used for sequencing.

Various WGA techniques have been developed. We provide services that accurately copy the original source DNA with the lowest false positive rate and validated protocol well-suited for detection of copy number variations and single nucleotide variations across the genome from a single cell after whole genome amplification.


  • to discover of CNVs and single nucleotide variations (SNVs) across genome in single cells or ultra-low input
  • to obtain a base-by-base view of an exome at single cell resolution

Single-Cell DNA Sequencing Workflow

The advent of cell sorting/partitioning technologies, such as flow cytometry and microfluidic, has made it possible to capture single cells, and WGA is optimized to providing high yields of whole genomic DNA for sequencing. The general workflow for single-cell DNA sequencing is outlined below.
