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 WebbReducing off-targets maximizes specificity A successful siRNA knockdown experiment must be both effective and specific. Horizon’s SMARTselection design algorithm (used for ON-TARGETplus, Accell, siGENOME and Lincode siRNA) provides a high degree of confidence that the targeted gene will be the only one silenced.
