HyperScribe™ T7 High Yield Fluorescein RNA Labeling Kit is designed to generate randomly fluorescein-modified RNA probes by in vitro transcription. Such probes are ideally suited for in situ hybridization and Northern blot hybridization experiments. The principle of labeling is similar to the basic labeling principle of a mixture of fluorescein RNA labels. Fluorescein-12-UTP is efficiently incorporated into RNA using the optimized reaction buffer and T7 RNA polymerase mixture in place of its natural counterpart UTP. An appropriate Fluorescein-12-UTP substitution typically achieves an optimal balance between reaction and labeling efficiency. However, the individual optimization of the Fluorescein-12-UTP / UTP ratio can be easily achieved using a single nucleotide format. The resulting fluorescein-modified RNA probe can then be detected by fluorescence spectroscopy.
