Dog and rat eyes shown by autoradioluminography. a Dog eye individually cryosectioned at 40 µm thick and imaged using phosphor storage technology. Adjustments to the gray scale appearance facilitate tissue identification for quantification. b Melanin association. A pigmented and albino rat eye exposed to the same test article. In situ samples as imaged by phosphor storage technology from whole-body cryosections. Differential distribution of the test article shows a high concentration in the pigmented uveal tract, while a lower concentration of radioactivity is seen in the uveal tract of an albino rat
