FD-1080 free acid

FD-1080 free acid is a fluorophore with both excitation and emission in the NIR-II region (Ex=1064 nm, Em=1080 nm). FD-1080 free acid can be used for in vivo imaging[1].

FD-1080 shows superior photostability under the continuous laser irradiation. The quantum yield of FD-1080 is 0.31%, and can be increased to 5.94% after combining with fetal bovine serum (FBS) to form FD-1080-FBS complexes[1].

The 1064 nm NIR-II excitation of FD-1080 is demonstrated with the high tissue penetration depth and superior imaging resolution compared to NIR excitation from 650 nm to 980 nm. Deeptissue and high-resolution in vivo imaging for the left hindlimb vasculature, abdomen, and brain vessels was realized, allowing penetration through intact skin, tissue, and skull. FD-1080 also quantifying the respiratory rate based on the dynamic imaging of respiratory craniocaudal motion of the liver for the awake and anaesthetized mouse[1].
