title: GSM6016002: fetal lung tissue, Sample5; Homo sapiens; miRNA-Seq
library_construction_protocol: Total RNA was extracted from 30mg of homogenized prenatal lung tissue with the miRNeasy Mini Kit per manufacturer instructions. Samples were block-randomized by age, sex, and smoke exposure status to four batches of miRNA library preparation (Small RNA Sequencing Kit v3 for Illumina Platforms; Bio Scientific) and sequencing (HiSeq2500; Illumina; San Diego, CA, USA).
