Double-stranded RNA (dsRNA) is a key molecular signature in viral infection/replication and a critical impurity in in vitro transcribed (IVT) RNA products, such as mRNA vaccines[1-8].
Check out our gold standard Anti-dsRNA monoclonal antibodies which are efficient tools for the detection of dsRNA in cell culture & tissues such as FFPE samples as well as in in vitro transcribed mRNA preparations[1-8] (Tab. 1).
Unsure which antibody fits best? Choose our Anti-dsRNA Comparison Set for comparative testing.
