The SiR fluorescent dye replaces the oxygen atoms of the rhodamine nucleus with silicon atoms, making it have the advantages of traditional rhodamine fluorescent dyes, and can also redshift the fluorescence wavelength to the near-infrared band, which is a good solution to the traditional rhodamine The short fluorescence wavelength meets the requirements of near-infrared biofluorescence imaging.

SiR fluorescent dye (silicorhodamine fluorescent dye) is a fluorescent dye that can easily penetrate the cell membrane and enter the cell, and has excellent fluorescence brightness and stability. Xi'an Confluore has a series of SiR fluorescent dyes to choose from, including: SiR-alkyne, SiR-azide, SiR-BCN, SiR-COOH, SiR-Maleimide, SiR-NHS ester, SiR-tetrazine, SiR650-BG, SiR700- BG and other dyes.
