Fluorescein-12-dUTP *1 mM in TE Buffer (pH 7.5)* *CAS 214154-36-6*
The dye-modified deoxyuridine 5'-triphosphates (such as aminoallyl-dUTP) can be used to produce dye-containing DNA by 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 fluorescein-dUTP conjugate can be used as a green fluorescence color with Spectrum Green™ filter set (Spectrum Green™ is the trademark of Vysis).

Important notes
Best stored at -80 °C, it can be diluted 10 folds in TE Buffer (10mM Tris-HCl + 1mM EDTA (pH=7.5)) for convenient pipetting. Expiration date is six months from the date of receipt.
