DAF-2T (Diaminofluorescein 2T) serves as a multifunctional dye utilized extensively across various domains. In the realm of biological experimentation, this dye facilitates the observation and analysis of cell structures, tracking of biomolecules, evaluation of cell functions, differentiation of cell types, detection of biomolecules, examination of tissue pathology, and monitoring of microorganisms. Its applications extend beyond fundamental scientific research into clinical diagnostics, highlighting its broad utility. Additionally, DAF-2T is employed in more traditional sectors like textile dyeing and in newer areas such as functional textile processing, food pigments, and dye-sensitized solar cells.
