Fluorescent dUTP can be used to synthesize labeled DNA probes for in-situ hybridization, microarray or blotting techniques. Cyanine 555 is structurally identical to Cy®3, and Cyanine 647 is structurally identical to Cy®5.

5-TAMRA-dUTP (5-Tetramethylrhodamine-dUTP) can be enzymatically incorporated into DNA. Note: 5-TAMRA-dUTP may not be compatible with PCR labeling of DNA probes.

DEAC-dUTP (diethylaminocoumarin-dUTP) can be used to synthesize fluorescent DNA probes for in situ hybridization, microarray or blotting techniques. DEAC has absorption at 426 nm and emission at 480 nm.

Fluorescein-12-dUTP can be used to synthesize fluorescent DNA probes.
