C 57 black × C 3 H F 1 hybrid male mice about 5 months old were injected intraperitoneally with 20 μC [8- 14 C]-adenine-HCl and killed from 1 to 32 days later. Autoradiographs of squashes and sections of various organs were prepared after treatment

Thin sections of methacrylate and Araldite embedded tissues labelled with radioactive isotopes were transferred with a wire loop or brush from the knife edge onto thin formvar membranes which covered 7 mm holes in 76 × 25 × 1.5 mm or 76 × 38 × 1.

Autoradiographs of adult mice killed at various times after injection of tritiated thymidine show significant numbers of labelled nuclei in organs in which mitoses are either very rare or completely absent. The proportion of labelled cells that divid

An account of theoretical considerations of the photographic action of x rays, based on the absorption process of x rays in photographic emulsions, and found to be in good agreement with experimental results, is presented in this paper. An equation g

The nucleic acids of various tissues were labelled by i.p. injection of [8- 14 C]-adenine and autoradiographs of 5 μ sections were prepared. It had previously been reported that spermotogonia synthesize labelled DNA for a period of up to eight days

So far autoradiography has mainly been used at the level of light microscopy and the theory of autoradiography was developed for this type of work. Whatever the intended application, the problems involved can be grouped under (a) resolving power, (b)

Italico rats were injected with thymidine-3H 6 hr after the end of 300 hr of intermittent cold treatment. This plan of experiment ensured replacement in the adrenal medulla of lost DNA which is specifically sensitive to cold treatment and has a label

The mitotic activity of the spleens of non-immunized germ-free (GF) mice was less than in similar specific pathogen-free (SPF) animals. No evidence of germinal center activity was noted in these GF mouse spleens before challenge with sheep erythrocyt

The hypothesis that all nuclei containing labelled DNA in the jejunum of adult mice divide before migrating into the villi and that the amount of labelled DNA is constant during the passage of cells through the villi was tested experimentally. Mice w
