Abstract
We describe a protocol that uses a bioinformatically optimized primer in an isothermal whole genome amplification (WGA) reaction. Overnight incubation at 37 degrees C efficiently generates several hundred- to several thousand-fold increases in input DNA. The amplified product retains reasonably faithful quantitative representation of unamplified whole genomic DNA (gDNA). We provide protocols for applying this isothermal primer extension WGA protocol in three different techniques of genomic analysis: comparative genomic hybridization (CGH), genotyping at simple tandem repeat (STR) loci and screening for single base mutations in a common monogenic disorder, beta-thalassemia. gDNA extracted from formalin-fixed paraffin-embedded (FFPE) tissues can also be amplified with this protocol.
