Whole genome amplification (WGA) of extracted DNA is carried out using a REPLI-g kit (Qiagen). The kit uses Multiple Displacement Amplification technology to produce highly uniform amplification across the genome. The genome is isothermally amplified utilizing a DNA polymerase with 3′ – 5′ exonuclease proofreading activity capable of replicating up to 100 kb without disassociating from the DNA template. Typical yields from the REPLI-g kit are 40ug DNA with a product range of 2 to 100 kb and an average of greater than10 kb. Poor quality genomic dna may result in synthesis failure, reduced call rates in downstream applications, or loss of loci or alleles in the amplification product.

Sample Preparation

We accept genomic DNA, whole blood, frozen blood, packed cells (buffy coats), blood spots, and cultured cells for whole genome amplification. Samples are amplified using Qiagen’s REPLI-g Midi Kit. OD is determined by pico green analysis using a Spectra Max Gemini XS fluorometer.  Concentrations will be returned to you in an Excel document. See below table for specifics on amount to send for each sample type and shipping conditions.
