title: High-throughput genotyping of factor V Leiden mutation by ultrathin-layer agarose gel electrophoresis.
abstract: Ultrathin-layer agarose gel electrophoresis is a novel combination of the established methodologies of slab gel electrophoresis and capillary gel electrophoresis. This new format provides a multilane separation platform with rapid analysis time and excellent sensitivity by using laser-induced fluorescence scanning detection system. Sample injection onto the ultrathin-layer separation platform is easily accomplished by membrane mediated loading technology. In this paper, we demonstrate the sensitivity and high-throughput fashion of this novel separation and detection system for rapid genotyping of the coagulation factor V Leiden mutation by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis. The PCR amplified fragment from exon 10 of the factor V gene was digested by the Mnl I restriction enzyme, followed by automated ultrathin-layer agarose gel electrophoresis analysis with "in migratio" fluorescent labeling during the separation process. Due to its speed and automation, this method should be considered for large scale screening of factor V Leiden mutation.
