Whole Genome Amplification

GenomePlex Overview

Move Beyond Traditional PCR Limitation...Unsurpassed Yield,
Unlimited Potential

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 including blood cards, whole blood, buccal swabs, soil, plant, and formalin-fixed paraffin-embedded (FFPE) tissues. 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. A number of downstream applications may be performed including TaqMan® assays, CGH analysis, SNP analysis, sequencing, etc.


  • Choose from a variety of DNA sources: whole blood, blood card, plasma, serum, buccal swab, plant, soil, formalin-fixed paraffin-embedded (FFPE) tissue and single cells

  • 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 in a few hours

  • Enjoy the compatibility GenomePlex provides with many downstream applications: TaqMan assays, SNP analysis, microarray analysis, sequencing, or store at -20 °C for future use
