Summary
SDS-polyacrylamide gel electrophoresis of isolated photoreceptor membrane from crayfish compound eyes in the absence and presence of the sulfhydryl-reducing agent 2-mercaptoethanol revealed major qualitative and quantitative differences in electrophoretic behaviour of polypeptides. Two peptides of 37 and 69 KD show abnormal migration patterns under the experimental conditions, indicating a possible significance of disulfide bridges for the structural integrity of invertebrate photoreceptor membrane.
