General description

Cy®7 Bis NHS Ester or N-hydroxysuccinimide ester is a commercially available fluorescent label. The two reactive groups present on each dye molecule enable the labeling of the molecules. NHS esters react with nucleophiles to release the NHS or sulfo-NHS group to create stable amide and imide bonds.

Application

Cy®7 Bis NHS Ester is used for HTS (High Throughput Screening) experiments.

It is a preferred fluorescent label for site-specific RNA labeling. The spectrophotometric assays using NHS esters are used to measure the active esters on carriers and the subsequent interaction with amines during peptide synthesis.

Storage and Stability

Please be aware this product may be shipped 90 days before the expiration date. For more information on the batch specific expiration date, please contact technical service.
Reconstituted material may be stored for up to 2 weeks at -20°C in aliquots to avoid repeat freeze thaw cycles.

Site-specific fluorescent labeling of RNA is crucial for obtaining the structural and dynamic information of RNAs by fluorescence techniques. Post-synthetic modification of RNA based on N-hydroxysuccinimide (NHS) coupling reaction is an economic, efficient and simple strategy to introduce fluorophore to
