Fluorescein-12-UTP is ideal for in vitro transcription reactions catalyzed by T3, T7, or SP6 RNA polymerases and reverse transcriptase to produce fluorophore-labeled RNA transcripts. RNA-based probes can be used to identify complementary sequences by in situ hybridization to fixed cells and tissues by direct or indirect fluorescence detection or by membrane hybridization procedures.
