Biological Activity for ICG-d7
Key information: ICG-d7 is a partially deuterated form of near-infrared fluorescent dye Indocyanine Green (ICG; Cat. No. 7510).
Application: Fluorescence microscopy, in vivo imaging.
Properties and Photophysical Data: ICG-d7 operates in the 700 - 900 nm wavelength range; also exhibits fluorescence emission in the shortwave infrared window (SWIR; 1,000 - 2,000 nm) which enables in vivo imaging. ICG-d7 shows improved stability in aqueous solutions over ICG with the same fluorescence brightness, and similar absorption and emission maxima in both DMSO and FBS. Excitation and emission maxima (λ) are 794 nm and 818 nm, respectively; quantum yield = 0.21; extinction coefficient = 228,000 M-1cm-1.
