Double-stranded (ds)RNA formation is a hallmark of viral infections that is essential for the induction of innate immunity. dsRNA is also involved in gene silencing and produced as side product during in vitro transription-based RNA synthesis. SCICONS Anti-dsRNA monoclonal antibodies are efficient tools for the detection of dsRNA in cell culture & tissues such as FFPE samples as well as in vitro transcribed (m)RNA preparations [1-7] (Tab. 1) e.g.
|Anti-dsRNA monoclonal antibody J2||Mouse, IgG2a, kappa light chain|| |
ELISA, IF, FACS, IHC, IP, Dot Blot, ChIP, affinity purification, immunoelectron microscopy
|Gold standard for dsRNA detection|
Recommended for quality control of in vitro transcribed (m)RNA
|Anti-dsRNA monoclonal antibody K1||Mouse, IgG2a, kappa light chain||Recommended for Poly I:C detection|
J2 alternative in case of cross reactions
Anti-dsRNA monoclonal antibody K2
Mouse, IgM, kappa light chain
ELISA, IHC, Dot Blot
|Isotype alternative to J2 & K1 |
Recommended for (Sandwich-) ELISA
|dsRNA 142 bp||synthetic dsRNA||Positive control for Anti-dsRNA monoclonal antibodies J2, K1 and K2||n/a|
