Measurements of NO photorelease for BODIPY-NOD-1 are obstructed because the absorption spectrum of this photoproduct overlaps with that of DAR-2 probe. It results in the background fluorescence increase during photolysis; however, the fluorescence of DAR-2 probe did not significantly exceed the background level, therefore we conclude that BODIPY-NOD-1 has low efficiency of NO photorelease.
