The GenomePlex® Complete WGA Kit (WGA2), contains the same reagents as the GenomePlex® WGA Kit (WGA1) as well as an optimized enzyme, WGA DNA Polymerase. This enzyme provides for increased accuracy in amplification, as evidenced by producing no amplicon in the negative control reactions. Observing no amplicon in the negative control reactions leads to more accurate down stream applications such as PCR or hybridization techniques.

The GenomePlex® WGA family of products are derived from the proprietary amplification method that is based upon random fragmentation of the genome into a series of overlapping, short templates. The resulting shorter DNA strands generate a library of DNA fragments with defined 3 primed and 5 primed termini, the OmniPlex® library. This library is replicated using a linear, isothermal amplification in the initial stages, followed by a limited round of geometric (PCR) amplifications.


WGA has been used in a variety of applications,1, 2 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.


Features
  • Increase amplification accuracy with WGA DNA Polymerase

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

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

  • See a complete representation of the entire genome with no detectable allele bias

DNA was extracted from a sample of formalin-fixed paraffin-embedded rat liver. 10 ng of genomic DNA (even lanes) and no template controls (odd lanes) were amplified using the GenomePlex® Complete WGA kit (WGA2) and competitor kits. All samples were purified with the GenElute™ PCR Clean Up Kit.


Accurate Amplification of Your DNA Target

GenomePlex®, a WGA kit, provides excellent representation and unsurpassed yield of the desired DNA without generating unnecessary primer assembly products.

DNA extracted from FFPE rat liver tissue was amplified using the Genomeplex WGA kit and competitor kits starting with 0ng, 10ng or 100ng input FFPE DNA. The Sigma-Aldrich kit provided no amplification product with 0ng of input DNA (as shown above), while competitor kits resulted in primer assembly products with 0ng of input DNA. Each of the WGA reactions were subjected to quantitative PCR (45 cycles) using 12 different primer sets. This data shows the targeted genes were more efficiently amplified (as shown by the number of cycles minus Ct values) with the GenomePlex kit as compared to the competitor kits.
