Sulfo-Cyanine 7.5 maleimide (A270304)

Sulfo-Cyanine 7.5 maleimide

sulfo-Cyanine 7.5 is a near infrared fluorophore with absorption and emission ranges around 800 nm. Its spectral properties allow for the efficient leveraging of tissue NIR transparency window. The fluorophore is available as different reactive forms, this one is maleimide for the labeling of SH groups of proteins and peptides. The sulfo- version is highly hydrophilic. Such labeled biomolecules are useful in biodistribution studies and visualization in intact organisms.
