Description:
dsRNA 142 bp is a chemically defined 142 bp long dsRNA sequence intended to be used as a positive control in double-stranded (ds)RNA detection. The sequence does not contain any viral or potentially transforming elements.

It is suitable for use as a size standard in dsRNA and RNAi analysis on both non-denaturing polyacrylamide and agarose gels. We suggest to use it as a homogenous, well-characterized positive control for different dsRNA detection methods, e.g. for ELISA and dot-blots.

Quality control:
Purity: absorbance spectrum and gel electrophresis
Activity: Sandwich-ELISA (relative activity to reference antigen)
