Figure 3. Photobleaching difference spectra for purified wild-type and mutant green opsins
Spectra were measured both prior to and following bleaching with light greater than 495 nm wavelength and differences were calculated. Difference spectra for wild type green (Grn-WT). Difference spectra for the N32S unglycosylated green cone opsin (Grn-N32S). Both show a [lambda]max at 530 nm.
