The Xenopus retina contains rods of two types: a blue-sensitive one Q,.. 2 445nm) and a principal rod (&._ z 522nm). We performed partial bleaching experiments on isolated retinas of Xenopus at different life stages and obtained the resulting difference spectra by transmission densitometry. The data showed that the blue-sensitive rod pigment is present in tadpoles, juveniles and adult animals in amounts not exceeding 15% of the total measurable pigment. Spectral sensitivity functions taken from… CONTINUE READING
