The probes were synthesized according to previous reports
using conventional phosphoramidite chemistry and purified by reversed-phase HPLC.25 The sequences used in this study are listed in
Table 1. The sequence of Kr-OMUpy2 is a 20-OMe ORN complementary to the 304–318 nucleotide position of the Kr-mRNA (GenBank
ID: 22024037). Kr-F is a 50-fluorescein labeled 20-OMe ORN which
has the same nucleotide sequence as Kr-OMUpy2. Kr-OMUnonpy is
