Background whole genome amplification wga is currently a prerequisite for single cell whole genome or exome sequencing.
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.
Reagents required for mda reactions include.
Methodology and applications annu rev genomics hum genet.
At very low levels of input dna successful amplification relies on reagent quality.
Single cell genomics is important for biology and medicine.
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.
However current whole genome amplification wga methods are limited by low accuracy of copy number variation cnv detection and low amplification fidelity.
Single cell genomiphi has been developed with this in mind.
Random primers and dna polymerase from bacteriophage phi29.
E coli as reference genome is an ideal model system to identify amplification bias introduced via technology used.
Multiple displacement amplification mda is a widely used technique enabling amplifying femtograms of dna from bacterium to micrograms for the use of sequencing.
The key parameters to characterize the performance of these methods are defined including genome coverage uniformity.
Single cell genomiphi dna amplification kit has been optimized to wholly amplify genomic dna from as little as a single cell generating micrograms of high quality dna for use in downstream applications.
Here we report an improved single cell wga method linear amplification via trans.
We present a survey of single cell whole genome amplification wga methods including degenerate oligonucleotide primed polymerase chain reaction dop pcr multiple displacement amplification mda and multiple annealing and looping based amplification cycles malbac.
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.
Epub 2015 jun 11.
A list of more than 100 different single cell omics methods have been published.
Depending on the method used the rate of artifact formation allelic dropout and sequence coverage over the genome may differ significantly.
