Cy5-UTP (Cyanine 5-aminoallyluridine-50-triphosphate) acts as a substrate for T7 RNA polymerase which could replace UTP with cyanine5-UTP. It is used to label RNA probes through in vitro transcription. The assembled mRNA will emit orange fluorescence and this incorporation allows RNA and mRNA detection independent of protein translation. Moreover, Cy5-labeled mRNA is visible under ultraviolet light without further staining after gel electrophoresis. Cy5-labeled RNA probes are used in a majority of molecular biology applications, such as mutagenesis, in situ hybridization, photo-cross linking studies and gene expression microarrays, etc.[1]

Analysis of oligonucleotide microarrays by 3' end labeling using fluorescent nucleotides and terminal transferase

Biotechniques2006 Jul;41(1):53-6.PMID: 16869513DOI: 10.2144/000112182

A simple enzymatic labeling procedure is described to determine spot quality in oligonucleotide microarrays. By using fluorescently labeled dideoxynucleotides or ribonucleotides as substrate for terminal deoxynucleotidyl transferase (TdT), a single fluorophore can be covalently attached at the 3' end of each oligonucleotide probe molecule in the spot. Fluorescein-12-ddUTP CyTM3-ddUTP Cy5-UTP, and Cy3-UTP were compared as TdT substrates for 3' end labeling an array of 1273 hexamer probes. Cy5-UTP was found to show minimal bias toward probe base composition and is therefore well suited for quantitative analysis of microarray spots where the oligonucleotide probes are coupled via a 5' end linkage to the solid phase.
