Single cell sequencing

At the Hubrecht Institute we have a special department for single cell sequencingJudith Vivié from the Van Oudenaarden group is our expert in the field. For any questions about using single cell techniques for your research please contact her:

About single cell sequencing 

A typical human cell consists of about 6 billion base pairs of DNA and 600 million bases of mRNA. With such huge amount of sequence, it is expensive and time-consuming to sequence by traditional Sanger sequencing. By using deep sequencing of DNA and RNA from single cell, cellular functions can be investigated extensively. Like typical NGS experiments, the protocols of a single cell sequencing generally contain the following steps: isolation of single cell, nucleic acids extraction and amplification, sequencing library preparation, sequencing and bioinformatic data analysis. It is more challenging to perform single cell sequencing in comparison with sequencing from cells in bulk. The minimal amount of starting materials from a single cell make degradation, sample loss and contamination exert pronounced effects on quality of sequencing data. In addition, due to the picogram level of the amount of nucleic acids used, heavy amplification is often needed during sample preparation of single cell sequencing, resulting in the uneven coverage, noise and inaccurate quantification of sequencing data.
