title: GSM5915194: Head_RNA_BD10-1; Drosophila melanogaster; RNA-Seq
library_construction_protocol: Total RNAs were isolated and dissolved in RNase-free water after the bulk samples had been homogenized in 0.5–1 mL TRIzol AG RNAex Pro Reagent (#AG21102, Accurate Bioeng. Co., Ltd., Hunan, China) with glass beads using a homogenizer. Poly-A RNAs were purified from the extracted total RNAs using Dynabeads™ Oligo(dT)25 (#61002, Invitrogen, CA, USA) and were further fragmented as ~350 nt fragments using NEBNext® Second Strand Synthesis (dNTP-Free) Reaction Buffer (#B6117S, New England BioLabs, MA, USA). Strand-specific sequencing libraries were conducted using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (#E7530L, New England BioLabs) according to the manufacturer's protocols including first- and second-strand cDNA synthesis, adaptor ligation, and library amplification with index sequences.
