# Quantitative comparison of single-cell sequencing methods using hippocampal neurons

## TL;DR

This study compares three DNA amplification methods for single-cell sequencing in hippocampal neurons to assess their reliability and accuracy.

## Contribution

The study provides a quantitative evaluation of MALBAC, MDA, and WGA4 methods for single-cell genomic analysis in hippocampal neurons.

## Key findings

- MALBAC and WGA4 methods showed high reproducibility and success rates in single-cell genome sequencing.
- Copy number variations at chromosome and subchromosomal levels were detectable among individual neurons.

## Abstract

Single-cell genomic analysis has grown rapidly in recent years and will find widespread applications in various fields of biology, including cancer biology, development, immunology, pre-implantation genetic diagnosis, and neurobiology. In this study, we amplified genomic DNA from individual hippocampal neurons using one of three single-cell DNA amplification methods (multiple annealing and looping-based amplification cycles (MALBAC), multiple displacement amplification (MDA), and GenomePlex whole genome amplification (WGA4)). We then systematically evaluated the genome coverage, GC-bias, reproducibility, and copy number variations among individual neurons. Our results showed that single-cell genome sequencing results obtained from the MALBAC and WGA4 methods are highly reproducible and have a high success rate. Chromosome-level and subchromosomal-level copy number variations among individual neurons can be detected.
