Using Multiplex PCR for Assessing the Quality of Whole Genome Amplified DNA.

This chapter describes a simple and inexpensive multiplex PCR-based method to assess the quality of whole genome amplification (WGA) products generated from heat-induced random fragmented DNA. A set of four primer pairs is used to amplify DNA sequences of WGA products in and downstream of GAPDH gene in yielding 100, 200, 300, and 400 bp fragments. PCR products are analyzed by agarose gel electrophoresis and the respective WGA quality is classified according to the number of obtained PCR bands. WGA products that yield three or four PCR bands are considered to be of high quality and yield good results when analyzed by means of array comparative genome hybridization (CGH).
