Biological dyes

Biological dyes include histological staining (tissue sections, immunohistochemistry, ELISA staining), plant and microbial staining (bacteria, fungi), and in vivo animal imaging (fluorescence, near-infrared, visible light). Among them, targeted fluorescent probes and bioluminescence imaging are used for precise tracing, while protease, luciferase and other enzyme dyes facilitate the study of specific molecular functions. These dyes are widely used in histochemistry, pathological analysis, in vivo imaging and life process monitoring, providing important tools for biological research.
