artus JCV RG PCR Kit CE
For quantitative detection of JC Virus (JCV) DNA using real-time PCR
The artus JCV RG PCR Kit is a real-time PCR test for the detection and quantification of JC Virus (JCV) specific DNA using real-time PCR on the Rotor-Gene Q.
Performance evaluation of the artus JCV RG PCR Kit was carried out using quantified JCV-specific DNA isolated from JCV strain MAD-1 (ATCC number: 45027).
The analytical sensitivity of the artus JCV RG PCR Kit, determined by probit analysis, for detection of JCV-specific DNA is 0.033 copies/µl (95% confidence interval [CI]: 0.013–0.175 copies/µl).
The analytical specificity of the artus JCV RG PCR Kit is ensured by careful selection of the oligonucleotides (primers and probes). The oligonucleotides are checked by sequence comparison analysis against publically available sequences to ensure that all relevant JCV genotypes are detected. In addition, the specificity of the artus JCV RG PCR Kit was evaluated by testing a panel of genomic DNA/RNA extracted from other pathogens. No cross-reactivity was shown.
The linear range of the artus JCV RG PCR Kit was evaluated by analyzing a logarithmic dilution series of DNA from JC virus strain MAD-1 using concentrations ranging from 1 x 109 to 0.1 copies/µl. At least six replicates per dilution were analyzed. The linear range of the artus JCV RG PCR Kit extends over an interval of at least eight orders of magnitude for JCV-specific DNA.
The artus JCV RG PCR Kit constitutes a ready-to-use system for the detection of JCV-specific DNA using real-time PCR on Rotor-Gene Q instruments. The assay includes a heterologous amplification system (Internal Control) to identify possible PCR inhibition and to confirm the integrity of the kit reagents.
Sample DNA is first extracted in a separate process e.g., using the QIAamp DNA Mini Kit (recommended extraction method). This is followed by detection of JCV-specific DNA using the Rotor-Gene Q.
The JCV RG Master A and JCV RG Master B contain reagents and enzymes for the specific amplification of target regions within the JCV genome and for the direct detection of the specific amplicon in fluorescence channel Cycling Green of Rotor-Gene Q instruments.
In addition, the artus JCV RG PCR Kit contains a heterologous amplification system (Internal Control) to identify potential failures during the assay process. The Internal Control is measured in the fluorescence channel Cycling Yellow of Rotor-Gene Q instruments.
Probes specific for JCV DNA are labeled with the fluorophore FAM. The probe specific for the Internal Control (IC) is labeled with the fluorophore JOE. The use of probes labeled with spectrally distinguishable fluorophores enables simultaneous detection and quantification of JCV DNA as well as detection of the Internal Control in the corresponding channels of the Rotor-Gene Q instrument.
The artus JCV RG PCR Kit is for in vitro diagnostic use for detection and quantification of JC Virus (JCV) specific DNA.
