The system is a clinical multiplex instrument intended to measure and sort multiple signals generated my multiple probes, intercalating dyes, or other ligands in an assay from a clinical sample. Signals may be generated by fluorescence or other phenomena and may be measured using filters on a photodiode or other detector. It may integrate sample and/or reagent handling, amplification, dedicated instrument control, data acquisition software, raw data storage mechanisms and other essential hardware components along with the signal reader unit. The system is used with specific assays to comprise an assay test system. A real-time thermocycler is intended to identify and/or quantify the presence of specific sequences of double stranded DNA, amplified from a biological source and labeled with fluorescently labeled probes or through the use of intercalating dyes and detect using a high-power light-emitting diode (LED). Fluorescence emission is detected through the use of filters on a photodiode. The emission filters are optimized for use with specific fluorescent dyes.
An electrically-powered laboratory instrument intended to amplify target deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) in a clinical specimen using heat-stable polymerase enzymes and cycles of repeated heating and cooling (i.e., thermal cycling) to replicate a product [i.e., a polymerase chain reaction (PCR)]. Amplified product is detected and/or identified using oligonucleotide markers as it is produced (i.e., in real-time) or at the end-point. The analyser may also isolate, extract and/or prepare nucleic acid from the clinical specimen and/or culture isolate prior to amplification, and operates with minimal technician input and complete automation of all procedural steps.
