Fig 4. Absorption spectrum of E17R in 20 mM Hepes, 100 mM NaCl, 0.03% DDM.

Fig 4

The inset shows the difference spectrum after bleaching with hydroxylamine. The extinction coefficient was calculated using the absorbance of the oxime product ΔA(oxime) in comparison to the bleached rhodopsin absorbance ΔA(Rh) as reference.
