Depositor Comments

Luciferase-reporter inserts were made by annealing oligonucleotides with their reverse complements, leaving overhangs for the indicated restriction sites (lower case): let-7-psm (gagctcACTATACAACCTACAAGCACAactagt). Annealed oligos were ligated into SacI/SpeI-cleaved pIS2. These plasmids were linearized with HindIII, polished with Klenow enzyme to create blunt ends, and digested with NotI to excise the Renilla luciferase gene with the modified UTR from the remainder of pIS2. The gel-purified Renilla gene fragment was then ligated into pMT-puro between EcoRV and NotI sites for copper-induced expression in S2 cells.
