Conjugation and labelingRhodamine
Rhodamine dyes are a class of fluorescent dyes with rhodamine as the core structure, with strong fluorescence characteristics and high quantum yield. They have a wide spectral range, covering visible light to near-infrared, and are suitable for multicolor fluorescence labeling and imaging. Due to their good photostability and cell membrane permeability, they are often used in biological analysis fields such as organelle labeling, protein tracing and in vivo imaging.
