Uses

Cyanine7.5 carboxylic 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 can be covalently bound to some biological molecules (especially antibodies, proteins, etc.) to track their location and dynamic changes in biological samples.
