Total RNA was isolated from ~2,000 synchronized day 5-adult worms using RNAbee (Tel-Test Inc.). cDNA was generated using qScript Flex cDNA synthesis kit (Quantabio). SybrGreen real-time qPCR experiments were performed with a 1:20 dilution of cDNA using a CFC384 Real-Time System (Bio-Rad). Data were analysed with the comparative 2ΔΔCt method using the geometric mean of cdc-42 and pmp-3 as housekeeping genes90 (link). See Supplementary Table 2 for details about the primers used for this assay.
