Negative control for ssRNA40/LyoVec™

ssRNA41 is a 20-mer phosphothioate protected single-stranded RNA oligonucleotide. It derives from ssRNA40 by replacement of all U nucleotides with adenosine [1].

ssRNA41 is complexed with the cationic lipid LyoVec™, to protect it from degradation and facilitate its uptake, and lyophilized to generate ssRNA41/LyoVec™.

Unlike ssRNA40, ssRNA41 is unable to induce the production of type IFNs, and therefore can be used as a negative control for ssRNA40 [1, 2].
