dc.description.abstract | We report a new, bioconjugate approach to performing highly multiplexed single-base extension (SBE) assays, which we demonstrate by genotyping a large panel of point mutants in exons 5-9 of the p53 gene. A series of monodisperse polyamide drag-tags was created using both chemical and biological synthesis and used to achieve the high-resolution separation of genotyping reaction products by microchannel electrophoresis without a polymeric sieving matrix. A highly multiplexed SBE reaction was performed in which 16 unique drag-tagged primers simultaneously probe 16 p53 gene loci, with an abbreviated thermal cycling protocol of only 9 min. The drag-tagged SBE products were rapidly separated by free-solution conjugate electrophoresis (FSCE) in both capillaries and microfluidic chips with genotyping accuracy in excess of 96%. The separation requires less than 70 s in a glass microfluidic chip, or about 20 min in a commercial capillary array sequencing instrument. Compared to gel electrophoresis, FSCE offers greater freedom in the design of SBE primers by essentially decoupling the length of the primer and the electrophoretic mobility of the genotyping products. FSCE also presents new possibilities for the facile implementation of SBE on integrated microfluidic electrophoresis devices for rapid, high-throughput genetic mutation detection or SNP scoring. © 2007 American Chemical Society. | - |
