1 pg of e coli dna has been amplified with either the repli g single cell kit or a kit based on malbac technology library prep and miseq sequencing similar data analysis on clc workbench.
Here we report an improved single cell wga method linear amplification via trans.
Depending on the method used the rate of artifact formation allelic dropout and sequence coverage over the genome may differ significantly.
Single cell whole genome amplification and sequencing.
In contrast a deep analysis of the genome currently requires a few hundred nanograms up to micrograms of genomic dna for library formation necessary for ngs sequencing or labeling protocols e g microarrays.
The key parameters to characterize the performance of these methods are defined including genome coverage uniformity.
Consequently accurate whole genome amplification wga of single cell dna is required for reliable genetic analysis e g ngs.

Multiple displacement amplification mda is a widely used technique enabling amplifying femtograms of dna from bacterium to micrograms for the use of sequencing.
Genomeplex single cell whole genome amplification kit utilizes a proprietary technology based on random fragmentation of genomic dna and conversion of the resulting small fragments to pcr amplifiable library molecules flanked by universal priming sites.
However current whole genome amplification wga methods are limited by low accuracy of copy number variation cnv detection and low amplification fidelity.
