Cy5-UTP
Cy5-UTP is a fluorescently labeled ribonucleotide triphosphate that can be used as a substrate for terminal deoxynucleotidyl transferase (TdT). Cy5-UTP can be employed to label RNA probes generated in vitro (Ex/Em: 650/665 nm). Cy5-UTP can be applied in FISH, multi-color fluorescence analysis, especially in dual-color expression arrays that combine with Cy5-UTP.

Biological Activity
Cy5-UTP (100 μM; 1 h) shows minimal bias toward the base composition of immobilized hexamer oligonucleotide probes, making it well suited for quantitative analysis of microarray spots where probes are coupled via a 5' end linkage to the solid phase[1].
Cy5-UTP (0.1-10% of total UTP pool) enables controllable, high-yield fluorescent co-transcriptional body labeling of FLuc mRNA via T7 RNA polymerase, with a linear relationship between Cy5-UTP input fraction and fluorophores per RNA, and 0.79% Cy5-UTP yielding 5 labels per mRNA[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
