Virus-Like Particles RNA (VLP-RNA) are for extraction control purposes of viral RNA and intended to help laboratories to control the quality of nucleic acid extraction from e.g. clinical samples by spiking the VLP-RNA into the sample before starting the respective extraction protocol. VLP-RNA is intended to be used as patient-side extraction control in combination with gerbion Real Time PCR kits. After amplification extracted RNA is identified in the VIC/JOE/HEX channel or 498-580 detection channel of the Roche LightCycler 480 II, respectively. The Control RNA of the respective kits can be substituted by VLPRNA. The VLP-RNA can also be used to support laboratory staff training in molecular assays from extraction phase through amplification to detection.
