RNAi

Search or browse a total of 415 RNA interference (RNAi) experiments available in LiceBase. RNA interference is a technique to "silence" a gene's expression by injection of double-stranded RNA (dsRNA) or short-interfering RNA (siRNA).
At SLRC, dsRNA has been widely used and can be applied at Nauplia and pre-adult and adult stages of the salmon louse. The animals are then compared to control animals for differences in phenotype. Most are only inspected visually, but some also histologically or measurements, e.g. of egg-string length. Note: "No visible phenotype" means that no difference could be observed under the outlined experimental conditions and using the observation methods applied.
