Balanced, robust whole genome amplification from single cells
The Ampli1™ Whole Genome Amplification (WGA) kit has been developed and optimized for balanced and complete amplification of the total DNA content of a single cell. The output of the Ampli1 WGA protocol is a well-balanced library of approximately 19 million fragments representing the entire genome. This DNA library is ideally suited for downstream analysis of both SNPs and CNV in single cells, due to its low rate of preferential amplification.
Single tube protocol ideal for all sample types
The Ampli1 WGA Kit is designed to provide optimal whole genome amplification—not only from samples containing DNA from a few cells, but from DNA obtained from one single cell. Input DNA may be derived from fresh, fixed, and/or stained cells.
Following cell lysis, DNA is digested with a restriction enzyme and adaptors are ligated onto the DNA fragments. Amplification, performed in the same tube, is mediated by a single highly specific PCR primer for all 19 million fragments.
Reliable, Reproducible, Balanced Single Cell Amplification
Key features of the Ampli1 WGA Kit:
Ampli1™ QC Kit
The Ampli1™ QC Kit provides a useful quality control check of the WGA procedure by utilizing a PCR-based assay to establish DNA integrity.
By testing for the presence of one short and three long DNA fragments in the WGA library, the quality of the DNA as starting material for downstream analyses can be assured.
Cells with good quality DNA typically produce 3 or 4 PCR bands, while fixation of cells or cells with degraded DNA will show fewer QC bands. It has been proved that the number of the bands revealed is useful to define a “Genome Integrity Index” (GII) for predicting success of various downstream analytical methods and for assessing the quality of the starting DNA.
Ampli1™ ReAmp/ds Kit
Ampli1™ ReAmp/ds Kit is design to reamplify the Ampli1 WGA product obtained from single cells, or from a batch of cells, in a reliable and reproducible way.
Reamplification will provide additional WGA-amplified DNA from the same cell. For downstream genetic analysis, you may use the Ampli1 Reamplification product in the same manner as Ampli1 WGA product.
Ampli1 ReAmp/ds Kit can also be used to convert ssDNA molecules into dsDNA molecules both in Ampli1 WGA products and in Ampli1 reamplification products in order to increase the total dsDNA content. This procedure is recommended for accurate DNA quantitation, high-throughput high dimensional downstream analysis, and NGS applications to ensure high sequencing uniformity.
