To investigate the antisense effect of a pyrrolidine-based oxy-peptide nucleic acid (POPNA), we carried out the LacZ reporter assay using a 12-mer trans-l-POPNA conjugated with a cell-penetrating peptide (antisense reagent). The antisense effect of the conjugated POPNA (inhibition of LacZ activity) was comparable to that shown by a Nielsen-type peptide nucleic acid. Furthermore, the conjugated POPNA could switch the LacZ activity over a wide range of ambient temperatures.
