title: GSM2221308: HeLa_WT_IP_rep3; Homo sapiens; RIP-Seq
library_construction_protocol: Cells were harvested in cold PBS and immediately lysed in M2 lysis buffer (50 mM Tris-HCl pH 7.5, 150 mM NaCl, 1 mM EDTA, 1% Triton X-100) containing 100 U/ml RNasin (Promega) and 2X protease and phosphatase inhibitors (Pierce). FLAG-tagged LIN28 variants were purified using the anti-FLAG M2 affinity gel following the manufacturer’s specifications (Sigma). Parental HeLa cells (no FLAG) were used as controls for antibody specificity. RNA was isolated from the beads using Trizol (Invitrogen) and RNeasy columns (Qiagen). Purified RNA was subjected to polyA selection using the NEBNext Poly(A) mRNA Magnetic Isolation Module (NEB). Libraries were prepared with the NEBNext Ultra RNA Library Prep Kit (NEB).
