iFluor®647-PEG12-dUTP

1 mM in TE Buffer (pH 7.5)

The dye-modified deoxyuridine 5'-triphosphates are one of the most common methods to produce dye-labeled DNA via conventional enzymatic incorporation methods such as reverse transcription, nick translation, random primed labeling, or PCR. This enzymatic fluorescence labeling method is widely used for both FISH probes and microarray-based experiments. This iFluor® 647-PEG12-dUTP conjugate has the same spectral properties as ChromaTide™ Alexa Fluor™ 647-dUTP. Its PEG12 spacer makes it much more effectively incorporated into DNAs by polymerase. It is used as a far-red fluorescence color with a SpectrumFRed™ filter set. It provides a bright signal that has high photostability and is not affected by pH. ChromaTide™ and Alexa Fluor™ are the trademarks of ThermoFisher, and SpectrumFRed™ is the trademark of Vysis.
