ICG Dyes for Click Chemistry

ICG Dyes for Click Chemistry

ICG exhibits an absorption maximum in the near infrared region (NIR) at ca. 800 nm with a slight absorption in the visible range, which results in low auto-fluorescence. The emission maximum is at 810 nm. This absorption/emission profile allows for tissue-penetrating excitation without causing tissue damage. Iris Biotech provides alkyne/azide/DBCO and tetrazine-functionalized derivatives suitable for further conjugation via Click chemistry.
