Description
ICG Carboxylic acid is a versatile near-infrared (NIR) fluorescent dye that plays a crucial role in bioimaging applications. This inactive form of indocyanine green (ICG) offers unique properties that make it valuable for researchers across various scientific disciplines.
It is a hexanoic acid moiety that is attached to the ICG fluorophore and its functional group is a carboxylic acid. The carboxylic acid group of ICG Carboxylic acid allows for various chemical modifications like esterification reactions, amide bond formation with primary amines, and activation for coupling to other functional groups. These modifications can be used to create targeted imaging probes or to alter the dye's pharmacokinetic properties.
ICG is FDA-approved for certain medical diagnostics, which can facilitate its use in translational research. Some key applications include angiography, lymph node mapping, tumor detection and imaging, perfusion studies, and ophthalmic imaging.
ICG Carboxylic acid is a powerful tool for researchers in fields ranging from molecular biology to clinical diagnostics. Its unique combination of NIR fluorescence, versatile conjugation chemistry, and potential for chemical modifications makes it an excellent choice for developing targeted imaging probes and studying biological processes in deep tissues. Whether used as a standalone fluorophore or as a building block for more complex imaging agents, ICG Carboxylic acid continues to play a crucial role in advancing our understanding of biological systems through fluorescence imaging techniques.

Advantages and Applications
1. Deep Tissue Imaging: The NIR fluorescence of ICG Carboxylic acid enables deep tissue imaging, penetrating further than visible light fluorophores. This property allows researchers to visualize structures and processes beneath the skin surface, making it invaluable for in vivo imaging studies.
2. Versatile Conjugation: ICG Carboxylic acid can be coupled with primary amines on small molecules or biomolecules using standard amide bond coupling conditions. This versatility allows for the creation of custom fluorescent probes tailored to specific research needs.
3. Reference Standard: The compound can serve as a reference standard for dye-conjugates, providing a basis for comparison in various experimental setups.
4. Excellent Optical Properties: ICG Carboxylic acid can be excited using 750-800 nm laser lines or LEDs, offering flexibility in imaging setups. Its high extinction coefficient ensures strong fluorescence signals, even at low concentrations.

Background
ICG Dyes
ICG is clinically approved NIR dye and used in medical diagnostics, in vitro, vivo and animal model study. NIR fluorescence allows to observe the deep image from the surface of skin and its usage spreads to a wide range of research fields. ICG fluorescence method is safe and cost effective technique and used in a wide range of medical fields such as breast cancer sentinel lymph node navigation, detecting cerebral vessels, coronary arteries and biliary trees, tracking tumor location, detecting small HCC, etc. The method has several advantages such as radiation free, compact instrumentation, real-time monitoring, easy operation, etc. The maximum excitation/emission values of ICG are 785/821 nm. When ICG is injected into a human body, it rapidly bound to plasma protein, mainly high-density lipoprotein, and generates red-shifted fluorescence (845 nm). ICG in aqueous solution is unstable over time, thus the fresh solution should be used for effective trials. BioActs provides ICG dye for biological research and medical diagnostics and also offers various reactive and functionalized ICG dyes for labeling of antibodies, peptides, proteins and ligands.
