Fig. 1 IDbox HSV 1/2 assay cassette showing reagent and sample reaction chambers. The sample is manually added and cassette placed in the instrument. The instrument automatically adds the internal control, performs proteinase K lysis, and binds magnetic silica beads. The beads are passed to wash chambers using magnetic bead transfer valves, and the purified nucleic acid is added to the PCR reaction chamber, which contains lyophilized primers, probes, and master mix. Real-time PCR proceeds on the instrument, and the signal and re-association curves are determined using fluorescent detectors.
