We incubated the expressed opsins in all vectors with 11-cis retinal in vitro, extracted the reconstituted visual pigments in the dark, and irradiated the pigments with monochromatic lights to check their photointerconvertibility, which was confirmed only in PrB expressed in SRα and PrV in pcDNA3.1.
As described above, cultivation of AAPs requires light dark cycles to enable them to form pigments in the dark and use them in the light.
