產品介紹

Cyanine7.5 NHS ester

Cyanine7.5 is a NIR dye with very long-wave emission. This product is amine-reactive derivative of this fluorophore.

Near infrared radiation readily penetrates tissues and can be used for imaging applications in vivo.

This product can be used for the labeling of various biomolecules containing amine groups, such as proteins and peptides, to track their distribution in organism in vivo by NIR imaging.

Increased rigidity of cen*ral polymethyne moiety allows to increase uantum yield by 20% pared to parent structure of Cy7.5® NHS.
