REPLI-g Cell WGA & WTA Kit
For parallel whole genome and whole transcriptome amplification from cells and limited samples
The REPLI-g Cell WGA & WTA Kit uniquely enables uniform whole genome amplification (WGA) and whole transcriptome amplification (WTA) in parallel reactions, allowing direct correlation of the genome with the transcriptome from very small samples (25–1000 cells). Dedicated buffers and reagents undergo a unique, controlled decontamination procedure to block amplification of contaminating nucleic acids by the REPLI-g method. The innovative lysis buffer effectively stabilizes cellular nucleic acids, ensuring accurate representation of both genomic DNA and RNA levels. Unbiased amplification of genomic DNA and total RNA or mRNA (poly A+) is achieved using innovative Multiple Displacement Amplification (MDA) technology and the novel REPLI-g SensiPhi DNA Polymerase. In contrast to PCR-based amplification technologies, high fidelity rates are increased up to 1000-fold, avoiding costly false positive or negative results.
The REPLI-g Cell WGA & WTA Kit is intended for molecular biology applications. This product is not intended for the diagnosis, prevention, or treatment of a disease.
Complete genomic and transcriptome coverage, with low experimental variabilityThe REPLI-g Cell WGA & WTA Kit contains the novel REPLI-g SensiPhi DNA Polymerase, as well as an optimized set of buffers and reagents for parallel whole genome amplification (WGA) and whole transcriptome amplification (WTA) from 25–1000 cells, or equivalently small samples. Following efficient cell lysis, (and complete removal of genomic DNA followed by sensitive reverse transcription for the WTA reaction), the kit utilizes Multiple Displacement Amplification (MDA) technology for complete and unbiased amplification of gDNA and cDNA (see figure Multiple Displacement Amplification (MDA) technology). cDNA amplified using the REPLI-g Cell WGA & WTA Kit demonstrates a high degree of reproducibility from experiment to experiment, with minimal “technical noise”, ensuring highly reliable results (see figure High level of experimental reproducibility and minimized technical noise). The amplified gDNA and cDNA can be easily used in a variety of downstream applications (see figure REPLI-g amplified cDNA and gDNA perform like gDNA in downstream experiments).
Ideal for analyzing the genomic and transcriptomic profiles of limited samplesThe REPLI-g Cell WGA & WTA Kit provides highly uniform, parallel amplification across the entire genome and transcriptome, with negligible sequence bias. Even from samples as low as 25 cells, the kit ensures reliable whole genome and transcriptome amplification, making it highly suited for analyzing the direct consequences of genotypic changes on transcriptomes (see figure Highly suited for simultaneous genomic and transcriptomic analysis from the same limited sample).
For use in a wide variety of research areasThe REPLI-g Cell WGA & WTA Kit efficiently amplifies gDNA and cDNA directly from cells and can be used with various samples that are often analyzed in clinical research, including tumor cells, stem cells, sorted cells, or other small samples (see table).
The REPLI-g Cell WGA & WTA Kit has been specifically designed to co-amplify genomic DNA and total RNA in 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.
The REPLI-g Cell WGA & WTA Kit provides highly uniform amplification across the entire genome and transcriptome, with negligible sequence bias. The kit uses Multiple 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
Genetic analyses often require large amounts of gDNA and cDNA, which can be challenging given the often small sample sizes. It is also not possible to obtain these 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, allowing one sample of a small 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):
The REPLI-g Cell WGA & WTA Kit allows uniform parallel amplification of all transcripts and genomic regions from one very 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.
