Modified Nucleotides
Cy5-UTP sodium salt
Quick view. We supply Cy5-UTP sodium salt as a dry fluorescent UTP analog for RNA labeling, FISH and fluorescence-based transcription assays. A public CAS number is not assigned for this exact form. Catalog target purity: ≥99%.

Product profile
Cy5-UTP sodium salt is classified as nucleotide or nucleotide analog.
Cy5-UTP sodium salt — Cy5-UTP sodium can support fluorescent RNA preparation, FISH probe development, multicolor imaging and in-vitro transcription labeling.
For Cy5-UTP sodium salt, dye-labeled nucleotides or amidites are bulkier than native monomers; incorporation efficiency, label density, photobleaching and light exposure should be controlled.
