Principle
The REPLI-g Cell WGA & WTA Kit has been specifically designed to co-amplifygenomic DNA and total RNAin parallel reactions from a very small sample, allowing direct correlation of the genome with the transcriptome. Regulation of transcription is driven by the genome in response to the environment. Mutations and variations in the genome, such as point mutations and copy number or structural variations, result in a variety of different genomes within species or within an organism (e.g., mosaic tissues and cancer). Some genomic variations may have a low influence on cellular or systemic regulation. Others can have a dramatic effect on transcription regulation and, ultimately, physiology. Because of the composite structure of tissues, analyzing the direct consequences of genotypic changes on transcriptomes can only be done with very small samples that are made up of identical cells. TheREPLI-g Cell WGA & WTA Kit provides highly uniform amplification across the entire genome and transcriptome, with negligible sequence bias. The kit usesMultiple Displacement Amplification (MDA) technology, which carries out isothermal gDNA/cDNA amplification utilizing a uniquely processive DNA polymerase capable of replicating up to 70 kb without dissociating from the DNA template (see figure Multiple Displacement Amplification (MDA) technology).
Unique components of the REPLI-g Cell WGA & WTA Kit
- All of the kit’s enzymes and amplification components undergo a unique, controlled decontamination procedure to ensure elimination of REPLI-g amplifiable contaminating DNA or RNA. Following the procedure, the kits undergo stringent quality control to ensure complete functionality.
- The unique lysis buffer effectively stabilizes cellular RNA and DNA. This ensures that the resulting RNA accurately reflects the in vivo gene expression profile, and that RNA and DNA stays intact, maximizing genome coverage for subsequent analyses.
- All enzymatic steps have been specifically developed to enable efficient processing of RNA or DNA for accurate amplification. For example, these processes include effective gDNA removal prior to cDNA synthesis for RNA amplification and enzymatic DNA preparation that ensures efficient DNA amplification.
- Novel REPLI-g SensiPhi DNA Polymerase is used for Multiple Displacement Amplification (MDA). It is a newly developed, high-affinity enzyme that binds DNA more efficiently, especially when DNA concentration is low in the reaction mixture. In addition, and in contrast to PCR-based methods, REPLI-g SensiPhi DNA Polymerase has strong proofreading activity that results in 1000-foldfewer errors. It also has strong strand-displacement activity, enabling replication of DNA through stable hairpin structures that are resistant to Taq-based whole genome and whole transcriptome amplification procedures.
Procedure
Genetic analyses often require large amounts of gDNAand cDNA,whichcan be challenging given the often small sample sizes. It is alsonot possible to obtainthese when correlating the genomic status with the transcription pattern of just one very small sample. Parallel whole genome amplification and whole transcriptome amplification overcome the limits of low DNA or RNA quantity, allowingone sample of asmall number of cells to be analyzed. The easy reaction setup, logical and streamlined processing steps, low handling time of just 20 minutes, and overall reaction time of only 4 hours for the complete, parallel amplification of gDNA and RNA, make the REPLI-g Cell WGA & WTA Kit procedure an easy and reliable method to use. The REPLI-g Cell WGA & WTA Kit contains reagents for the following sequential reactions (see figure REPLI-g Cell WGA & WTA Kit procedure):
- Lysis of cells: a sample (containing 25–1000 cells) is lysed efficiently within 5 minutes, with no effect on RNA or DNA integrity. Lysed cells are divided into two aliquots of equal volume. The first aliquot is used for WGA, while the second aliquot is used for WTA of total RNA, or alternatively, mRNA-enriched (poly A+) RNA.
- Whole genome amplification: following cell lysis, DNA from one of the aliquots is modified for high efficiency ligation. Due to the nature of the ligation reaction, DNA fragments are not assembled in the order in which they would have originally existed in the organism. However, this does not affect detection of nucleic acid sequences (e.g., polymorphisms) in downstream applications, such as NGS, array analysis, or qPCR. After ligation, amplification using MDA technology and the novel, high-affinity REPLI-g SensiPhi DNA Polymerase takes place.
- Whole transcriptome amplification: following cell lysis, gDNA is removed from the second aliquot prior to starting the WTA process, since accurate measurement of transcript levels depends on the elimination of false-positive results caused by gDNA contamination. cDNA is prepared for high efficiency ligation and amplification. Depending on the primer chosen during the subsequent reverse transcription reaction, all transcripts for total RNA enrichment or only polyadenylated transcripts for poly A+ mRNA enrichment will be amplified.
Applications
The REPLI-g Cell WGA & WTA Kit allows uniform parallel amplification of all transcripts and genomic regions from onevery small sample. gDNA and cDNA amplified in parallel by the kit are highly suited for next-generation sequencing (both DNA-Seq and RNA-Seq*), analysis using arrays, genotyping applications, or quantitative PCR.
