Fig. 4. Validation of RNAi-mediated silencing of AamOatp. three ticks that
were injected with GFP-dsRNA or AamOatp-dsRNA were manually detached
at 48 h post-attachment. These ticks were individually processed for total RNA
extraction. Extracted total RNA was DNAse treated and then subjected to
two-step RT-PCR. PCR products were electrophoresed on a 2% agarose gel
containing 1 µg ml–1 of ethidium bromide. The numbers
represent individually treated ticks.
