摘要: Sustainable DNA resources and reliable high-throughput genotyping methods are required for large-scale, long-term genetic association studies. In the dissection of common disease it is now recognised that thousands samples hundreds markers, mostly single nucleotide polymorphisms (SNPs), will have to be analysed. order achieve these aims, both an ability boost quantities archived genotype at low costs highly desirable. We investigated Φ29 polymerase Multiple Displacement Amplification (MDA)-generated product (MDA product), in combination with multiplexed BeadArray™ technology. As part a large-scale BeadArray experiment we made direct comparison data generated from MDA genomic (gDNA) templates. Eighty-six corresponding 86 gDNA were genotyped 345 SNPs concordance rate 98.8% was achieved. The sample exclusion rate, blind type, 10.5% compared 5.8% gDNA. conclude technology successfully produces high quality product. technologies improves feasibility efficiency mapping susceptibility genes despite limited stocks samples.
