Will be supplied as ''Fluorescein-12-dUTP''. Unit of measure is ''nmol''.
For other than the listed concentrations please inquire.
Enzymatic nonradioactive labeling reagent for cDNA synthesis, PCR, random primed labeling, nick-translation or primer extension.
Use Fluorescein-12-dUTP as a substrate for:
  • Terminal Transferase
  • DNA polymerase I (holoenzyme and Klenow fragment)
  • Taq DNA polymerase
  • Reverse transcriptase (e.g., from AMV and M-MuLV)
Fluorescein-12-dUTP replaces dTTP in the random-primed DNA labeling reaction or in nick translation reactions, as well as in PCR. The nucleotide also serves as a substrate for Terminal Transferase in 3'-end labeling.
Fluorescein-labeled probes can be used for in situ hybridization with direct fluorescence detection and detection by ELISA using Anti-Fluorescein-AP, Fab fragments.
Repeated fluorescence labeling using Tetramethylrhodamine-6-dUTP (red) and AMCA-6-dUTP (bright blue) is possible.
