VariSafe™ RNA Controls
Looking for safe assay controls for highly infectious viruses or foreign animal diseases? Varizymes offers a selection of VariSafe RNAs: nuclease-resistant, single-stranded RNAs suitable as process controls for RNA extraction from various sample matrices. These specially engineered, non-infectious, MS2 phage-like particles protect their contents from degradation by nucleases and can package sequences of up to 1.5 kb from viruses such as SARS-CoV-2, Foot-and-Mouth Disease Virus, and Human Immunodeficiency Virus. We also offer made-to-order VariSafe RNAs (contact us for details).
