Modified Nucleotides
Fluorescein-12-UTP Sodium Salt
Quick view. A fluorescein-labeled ribo-UTP sodium salt in which the label is connected through a 12-atom aminoallyl-amide-derived linker at uracil C5. Sodium stoichiometry is not fixed in the reviewed identity sources. A public CAS number is not assigned for this exact form. Catalog target purity: ≥98%. Availability: Inquiry only — contact BX Lab to confirm current availability.

Product profile
Fluorescein-12-UTP Sodium Salt is classified as modified nucleotides.
Fluorescein-12-UTP Sodium Salt is suited for fluorescent probe preparation, RNA/DNA labeling, imaging readouts, gel visualization or assay-traceability studies where an optical signal is required.
For Fluorescein-12-UTP Sodium Salt, dye-labeled nucleotides or amidites are bulkier than native monomers; incorporation efficiency, label density, photobleaching and light exposure should be controlled.
