Description

Free unactivated Cyanine7.5 NIR dye carboxylic acid.

For coupling and labeling reactions also consider using pre-activated Cyanine7.5 NHS ester.

Uses

Cyanine7.5 carboxylic acid chloride is a dye derivative of Cyanine 7.5 (Cy7.5) (HY-D0926) with carboxylic acid functional groups. Cy7.5 is a near-infrared fluorescent dye commonly used in biomedical research areas such as biomarkers and cell imaging. Cyanine7.5 carboxylic acid chloride can be covalently bound to some biological molecules (especially antibodies, proteins, etc.) to track their location and dynamic changes in biological samples.
