Drosomycin expression was determined from five independent biological samples consisting of 5 infected third instar larvae following infection. Samples were compared to banana-fed flies of the corresponding time point. Larvae were collected at the desired time points and washed in 100% ethanol and sterile water. RNA was extracted using Purification Plus Kit (48400, Norgen – Biotek, Canada) and cDNA was prepared from 0.5 µg total RNA using
Maxima First Strand cDNA Syntesis Kit (K1672, Thermo Scientific, UK). Triplicate cDNA samples were amplified with the
SensiFASAT SYBR No-ROX Kit (BIO-98020, Bioline, UK) in a
Corbet Rotor-Gene 6000 QPCR machine (Qiagen, UK) according to the manufacturer’s protocols. Expression values were calculated using the DDCt method and normalized to rp49 expression levels (Schmittgen and Livak 2008 (
