Microautoradiography of ¹²⁵I-labeled peptides in the liver or spleen of AA mice at 1 h pi. Tissue sections from mice injected i.v. with ¹²⁵I-labeled peptides and euthanized at 1 h pi were exposed to photographic emulsion for 96 h before being developed. Radiolabeled peptide was visualized as punctate silver grains (arrows). (Magnification: 40×.) For display, the images were scaled to 10% of their original size.
