Webbpotential off-target effects of a given siRNA can be carried out using the C911 method37. siRNA bases 9–11 are mutated while the seed region (bases 2–8) remains intact. This maintains off-target interactions mediated by seed region matches but perturbs on-target silencing. c On-target specificity by phenotypic rescue can be demonstrated Webb2 feb. 2015 · However, because siRNA off-target effects occur through the miRNA pathway, tools for miRNA target site prediction (17,18) can also be used to predict siRNA off-targets.
