Viral RNA purification kits provide necessary reagents for the isolation of minute amounts viral RNA from samples such as blood, plasma, serum, or bodily fluids. These kits can provide high-quality yields of contamination-free RNA for downstream use in applications such as RT-PCR, microarrays, and other PCR-based assays. These ready-to-use kits can come in various formats, such as spin column, magnetic-based, and multi-well for higher throughput capabilities. Some also allow for the simultaneous collection of DNA.
