The TSA Fluorophore CM780 offers near-infrared fluorescence, which is particularly useful for multiplexing in immunohistochemistry. Using the same HRP-TSA principle, CM780 binds covalently to tissue antigens, ensuring excellent signal specificity and sensitivity. Its near-infrared emission provides excellent separation from visible fluorophores, making it an effective option for highly multiplexed assays where clear signal differentiation is required.
