| 摘要 |
An integrated droplet actuator device and methods are provided for performing PCR amplification and high-resolution melting (HRM) analysis on a single droplet actuator. HRM analysis can be used in combination with PCR amplification for detection of sequence variations (e.g., single-nucleotide polymorphisms, nucleotide-repeat polymorphisms, mutation scanning and assessment of DNA methylation) within one or more genes of interest. The PCR amplicons can be fluorescently labeled during amplification using a saturating DNA intercalating fluorescent dye, a 5′-labeled primer, or labeled probes. Also provided are a droplet actuator device and methods for sample preparation using the droplet actuator and detection of sequence variations on the same droplet actuator.
