The AccuSpan HCV RNA Linearity Panel (2410-0327) is an eight-member panel made from serial dilutions of high titer recombinant Hepatitis C virus (genotype 1b) with established reactivity for HCV RNA and one negative member. This panel consists of seven members representing serial log dilutions of AccuPlex recombinant HCV in negative diluent and one negative member prepared from the diluent. The diluent was prepared from pooled K3 EDTA plasma that was filtered through a 0.2 micron filter. Sodium azide (0.09%) was added as a preservative. This panel can be used for monitoring HCV RNA recovery at defined intervals, identifying consistency over a linear range, verifying lot changes, performing linearity studies, or whenever there are indications of possible assay deterioration. For Research Use Only. Not for use in diagnostic procedures.
