Cy7 NHS ester
Amine reactive Cy7, near infrared (NIR) fluorescent dye.
NIR fluorophores can be used to take advantage of near infrared window of biological tissues. Highly increased transparency of tissues in this spectral region allows in vivo imaging.
This reagent can be utilized to produce Cy7-labeled biomolecules, which can be subsequently used in various research and drug design related experiments.
This particular Cy7 structure 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. Water-soluble Cy7 NHS ester is also available, and is recommended for protein labeling.
