    • In all experiments described in this manuscript, the preincubation with RNase H, and translation were performed in total volumes of 7.6 and 10 μL, respectively. The unit of RNase H is defined by the manufacturer (Takara Bio). The translation time was set at one hour because it is known that the wheat germ extract used here ceases mRNA translation after 1 hour in a batch reaction, and because a larger amount of the transcribed protein in the -target state is better for detection; see

    • Incidentally, in a comparison between the same lengths of antisense DNAs, the one lacking the 3' terminus showed a higher inhibitory efficiency. This is probably because a 5'-CAT-3' sequence corresponding to the start codon resides nearer the 5' terminus, and/or because pyrimidine bases (C and T) are concentrated in the 5' terminus. A base pair between a pyrimidine in DNA and a purine base in RNA is stronger than the reverse; see

    • However, the method did not work well in the detection of the target in human serum (no translation occurred in the absence of the target, probably as a consequence of mRNA degradation). This suggests that samples must be cleaned before detection.
