Automated system for isolating, amplifying and detecting a target nucleic acid sequence

Abstract

A system and method for preparing and testing of targeted nucleic acids is presented. The system integrates a pipetter, extractor, assay reader, and other components, including a selectively compliant articulated robot arm (SCARA). This synergistic integration of previously separate diagnostic tools creates a system and method whereby a minimum of human intervention is required. The resulting system provides a substantially more accurate and precise method of isolating, amplifying and detecting targeted nucleic acids for diagnosing diseases.
