abstract = {Two molecular beacons were designed as complementary
fluorescent imaging probes for miRNA-21 and miRNA-31. Both
beacons were prepared by a combination of solid-phase
protocol and Cu(i)-catalyzed cycloaddition chemistry. The
four photostable and bright fluorophores were attached to
2'-positions in the stem part of the two beacons. One beacon
was labeled by a green-to-red emitting and the other by a
blue-to-yellow emitting energy transfer pair. This two by
two combination yields the four color emission readout. In
vitro experiments demonstrate rapid and highly selective
opening of both molecular beacons upon addition of the
complementary target RNA and excellent green : red and
blue : yellow emission color contrasts. Confocal
microscopy of selected cancer cell lines provides evidence
that a four color imaging of versicular miRNA-21 and
miRNA-31 can be achieved both selectively and simultaneously
upon transfection by the beacons, and that the fluorescent
readouts track well with miRNA levels determined by PCR.},
