Varizymes provides novel enzymes and reagents that advance low complexity molecular amplification and detection technologies. The company has engineered and purified several hundred proteins for customers and for commercial use. VariSafe RNAs are 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 from any virus.
