title: GSM8242061: sRNA-seq, set-21(red109);set-32(red11) anti-f15d4.5+c38d9.2 piRNAi, rep 1; Caenorhabditis elegans; ncRNA-Seq
library_construction_protocol: Small RNA was extracted using mirVana miRNA isolation kit (ThermoFisher). The small RNA libraries were constructed using a 5' - monophosphate independent, 3' and 5' linker ligation-based methods. ligation-based strategy
