Figure Lengend Snippet: Integrated optical density (IOD) of DNA bands after conventional reverse transcription PCR (RT–PCR) ( B ) and agarose gel electrophoresis ( A ). An equal amount of RNA taken from the T7 RNA polymerase reaction served as a template. The control sample contained a PNA oligomer that was not complementary to the PCSK9 coding sequence. This sample was arbitrarily assigned a value of 100%. In Panel ( B ), dashed line bars represent real-time PCR, while white dotted black bars represent conventional PCR after 15 cycles, in comparison to the control PNA. *— p < 0.05 vs. ctrlPNA for RT-PCR, #— p < 0.05 vs. ctrlPNA for conventional PCR.

Figure Lengend Snippet: Western blot image of an in vitro transcription/translation reaction product resolved by electrophoresis with appropriate integrated optical density (I.O.D) values ( A ) and the relative amount of protein with respect to control sample ( B ). 1–4: Samples that contained InitPNA, Ex1PNA, Ex2PNA, and control (non-PCSK9 specific) PNA, respectively. M: Color Prestained Protein Standard, Broad Range (New England Biolabs, no. Cat. P7712). The PCSK9-specific band is depicted with an arrow. A total amount of 10 µg (25 µL sample volume) of purified products from the transcription/translation reaction was loaded onto the gel. The initial protein concentration in the samples was assessed spectrophotometrically. Measurements were made using ImageJ 1.53t software [ , ] *: p < 0.05 vs. control.

Figure Lengend Snippet: The representative HPLC traces of GFP-tagged PCSK9 synthetic protein after addition of PNA oligomers ( A ). Area under the curve (AUC) values were calculated for each sample (run in triplicates) from chromatography peaks of GFP-tagged PCSK9 protein synthesized with the presence of different PNA oligomers ( B ) *: p < 0.05 vs. CtrlPNA.
