Cy7-N-羥基琥珀酰胺酯|CAS 477908-53-5|Sulfo-cyanine7 NHS ester



該試劑在標記時需要共溶劑有機溶劑。水溶Cy7 NHS ester可以用于蛋白NIR標記。

Amine reactive Cyanine7, near infrared fluorescent dye, an improved analog of Cy7?.

NIR fluorophores can be used to take advantage of near infrared window of biological tissues – increased transparency of tissues in this spectral region allows to carry out in vivo imaging.

This reagent can be utilized to produce Cyanine7-labeled biomolecules for subsequent use in various in vivo research, and drug design related experiments.

The structure of Cyanine7 features rigidized design of central polymethyne chain. This molecular reinforcement allows to increase quantum yield by 20% compared with parent structure, increasing fluorescence brightness.

This reagent requires organic co-solvent for the labeling (please see Recommended Protocols section below). Water-soluble Cyanine7 NHS ester is also available, and recommended for protein NIR labeling.
