← ScienceWhich consequence results when mismatch occurs between fluorophore emission/sensor absorption functions?
A)Reduced FRET efficiency observed✓
B)Increased signal-to-noise ratio occurs
C)Faster fluorophore photobleaching transpires
D)Ratiometric measurement errors amplified
💡 Explanation
Reduced FRET efficiency happens because dipole-dipole interactions require spectral overlap, impairing Förster resonance energy transfer; therefore, the energy transfer suffers, rather than enhanced signal or photobleaching, due to inefficiency.
