Criteria of applicability for autoradiography of tritium.
Autoradiography is an effective tool for the imaging of radionuclide distributions in various samples. In sophisticated applications with special preparation and development of sample-emulsion combinations and subsequent grain counts it can be highly quantitative, but it requires carefully controlled conditions and a variety of counter-checks, for example through scintillation spectroscopy. Les...
متن کاملElectron Microscopic Autoradiography
An improved method has been developed for the preparation of autoradiographs for electron optical study. The refinement lies principally in the routine production of uniformly thin layers of photographic emulsion over the tracer-labeled cell sections. This is accomplished by means of a centrifugal spreading mechanism. Maize root tips grown in the presence of H(3)-thymidine were examined electro...
متن کاملElectron Microscopic Autoradiography
Iodide is concentrated from the blood by the thyroid gland; after oxidation it is incorporated in tyrosyl residues of the thyroglobulin molecule. Thus the halogen is stored as a component of thyroglobulin in the colloid of the thyroid follicle. Secretion of thyroid hormone is considered to require proteolysis of the thyroglobulin and release of iodinated thyronines from the base of the acinar c...
متن کاملQuantitative Electron Microscopic Autoradiography
Quantitative electron microscopic autoradiography was used for comparing the binding of labeled somatostatin-14 (S-14) and somatostatin-28 (S-28) to islet cells. Monolayer cultures of rat islet cells were incubated with ['251-Tyr"jS-14 (S-14) or [125I-Leu8, D-Trp22, TyreJS-28 (S-281) in the presence or absence of excess unlabeled peptides. Autoradiographic grains (ARG) associated with individua...
متن کاملAnalysis of Tritium Incorporation into Individual Cells by Autoradiography of Squash Preparations
The relation between tritium content of individual cells and grain count obtained in autoradiographs of squashed cells was investigated. The tissues used were root meristems of Tradescantia paludosa and intestinal epithelium of the mouse. The relation between grain count and tritium content is affected by self-absorption which depends on the thickness of the labeled cell. Therefore, squashed pr...
