Description
artus VZV PCR Kits are ready-to-use molecular detection kits for real-time PCR. The kits provide all necessary reagents optimized for reliable VZV DNA detection and quantitation for in vitro diagnostic use. artus VZV LC, RG, and TM PCR Kits use manual or automated sample preparation and manual assay setup techniques. The artus VZV RG PCR Kit is also available as EASY artus VZV RG PCR Kits, which include the EZ1 DSP Virus Kit for automated viral nucleic acid purification. The artus VZV QS-RGQ Kit is part of the QIAsymphony RGQ, the complete automated system from sample to pathogen detection, and is not for use with manual assay setup.
To ensure highest sensitivity, artus VZV Kits have been optimized to detect low numbers of VZV DNA. The analytical sensitivity of the artus VZV QS-RGQ Kit is 19.2 copies/ml in consideration of the purification from plasma and assay setup using the QIAsymphony RGQ (see figure "Highly sensitive detection of VZV DNA").

artus VZV Kits are based on the amplification and simultaneous detection of a specific region of the VZV genome using real-time PCR. The kits provide high levels of specificity, sensitivity (see figure "Highly sensitive detection of VZV DNA"), and reproducibility. Each artus VZV Kit provides 4 VZV quantitation standards (see figure "Reliable quantitation of VZV load"). Use of the standards enables accurate quantitation of viral load. In addition, the kits contain a second heterologous amplification system to identify possible PCR inhibition. This is detected as an internal control (IC) in a different fluorescence channel from the analytical PCR. The detection limit of the analytical VZV PCR is not reduced.

artus VZV PCR Kits provide all necessary reagents optimized for reliable VZV DNA detection and quantitation. Simply add template DNA to the ready-to-use PCR master mix, and start the reaction on the appropriate real-time cycler using the optimized cycling program described in the kit handbook. Common temperature profiles for multiple assays in one run The temperature profile of the artus VZV LC PCR, RG PCR, and QS-RGQ Kits corresponds to the profiles of the artus LC PCR, RG PCR, and QS-RGQ Kits for CMV, EBV, and HSV-1/2, as well as for BK virus (RG and QS-RGQ only). Therefore, these PCR assays can be performed and analyzed in a single run. Complete automated system from sample to VZV detection The QIAsymphony RGQ workflow solution for VZV detection comprises the QIAsymphony SP for sample preparation, the QIAsymphony AS for assay setup, and the artus VZV QS-RGQ Kit on the Rotor-Gene Q. The system enables reliable pathogen detection with a complete CE-IVD-compliant workflow (see figure "Integrated QIAsymphony RGQ system for VZV detection"). Recommendations for viral DNA purification when using the artus VZV LC, RG, or TM PCR Kits For DNA purification, the EZ1 DSP Virus Kit is to be used or, depending on the sample type and artus VZV PCR Kit, the QIAamp DNA Mini Kit or QIAamp UltraSens Virus Kit. The artus VZV RG PCR Kit is also available as CE-IVD-marked EASY artus VZV RG PCR Kits, which include the EZ1 DSP Virus Kit for automated viral nucleic acid purification.
