SiR-PEG4-Maleimide

Silicon rhodamine sir (silicon rhodamine) dye is a dark red near-infrared fluorescent dye with strong cell permeability and high specificity It has good biocompatibility. Its excitation wave length is usually greater than 600 nm, and its emission wavelength is about 680 nm in the near-infrared region. Compared with the traditional near-infrared cyanine dye, silicon-based rhodamine has better optical stability, can obtain stable and lasting fluorescence signals in biological imaging, and can be applied to the long-term fluorescence imaging process.
