The gecko visual pigment: a pH indicator with a salt effect
AUTOR(ES)
Crescitelli, Frederick
RESUMO
1. Unlike rhodopsin, the extracted 521-pigment of the Tokay gecko (Gekko gekko) is pH-sensitive and changes its spectral absorbance in the pH range of 4.5-7.3. The colour change is reversible and pH can be employed to adjust the spectral maximum anywhere between 490 nm and its native location at 521 nm.
