Whole Genome Amplification

The GenomePlex^® Whole Genome Amplification (WGA) family of products provides a robust and accurate method of amplifying nanogram quantities of starting material into microgram yields with minimal allele drop out.
The GenomePlex WGA product line utilizes a proprietary amplification technology based upon random fragmentation of genomic DNA and conversion of the resulting small fragments to PCR-amplifiable OmniPlex^® Library molecules flanked by universal priming sites. The OmniPlex library is then PCR amplified using universal oligonucleotide primers and a limited number of cycles.
WGA has been used in a variety of applications,^{1, 2, 3} and is suitable for use with purified genomic DNA from a variety of sources. GenomePlex WGA uses nanogram quantities of starting genomic DNA, which after PCR yields 5 to 10 μg of WGA product. After purification, the WGA product can be analyzed in a manner similar to any genomic or chromosomal DNA sample.

• Choose from a variety of DNA sources: whole blood, buccal swab, blood card, plant, soil and formalin-fixed paraffin-embedded (FFPE) tissue
• See a complete representation of the entire genome with no detectable allele bias.
• Increase amplification accuracy with WGA DNA Polymerase
• Preserve precious source material by amplifying nanogram amounts of starting genomic DNA into microgram yields (on average up to 500fold) in less than three hours
• Enjoy the compatibility GenomePlex provides with many downstream applications: TaqMan^® assays, CGH analysis, SNP analysis, sequencing, or store at 20 °C for future use.
