New Indocyanine Green (Cat No.:M033558) is a derivative of the traditional Indocyanine Green dye but with enhanced properties for medical imaging and diagnostics. ICG is known for its ability to provide near-infrared fluorescence, which is ideal for visualizing vascular structures, lymphatic systems, and organ perfusion during surgery. The “New” formulation typically indicates improvements in stability, solubility, or fluorescence intensity, enhancing its effectiveness in clinical applications such as angiography, cancer detection, and intraoperative imaging.
