title: GSM4774710: tNet-PIPseq Proteinase K+Rnase V1+ RNaseOne treated WT pol II; Homo sapiens; OTHER
library_construction_protocol: Following RNAase digestion, samples with treated with Proteinase K at 1mg/ml  for 15mins at 37º and then 65 º for 30mins to reverse crosslinks.  RNA was purifed with trizol extraction and RNA fragments were convereted into sequencing libraries with lexogen small RNA kit.
