The plasmids
pmCherry-C1 and
pMetLuc2-Control were purchased from Takara Clontech (Kyoto, Japan). pmCherry-PAL and pMetLuc plasmids with aptamers in the 5’UTR were generated using the
In-Fusion HD EcoDry Cloning Kit (Takara Clontech, Kyoto, Japan). Previous PCR amplification used the primer pair:
5’- CTCAAGCTTCGAATTCATGAAGGTGAACCGGCCC 3’
5’- TAGATCCGGTGGATCCCTACGACGCCAGCTGCTCCAA 3’
pmCherry-C1 was linearized using EcoRI and BamHI. Primers for the aptamer inserts were:
Primers for the linearized
pMetLuc2-Control plasmid were:
HeLa cells (CLS Cell Lines Service GmbH, Eppelheim, Germany) were cultured in DMEM medium (high glucose,
GlutaMAXTM, Thermo Fisher Scientific, Darmstadt, Germany) supplemented with 10% fetal calf serum (FCS, Sigma-Aldrich, St. Louis, Missouri, USA) at 37ºC and 5% CO
2, and were passaged every 2 to 3 days.
