The Use of Radioautography in Investigating Protein Synthesis

The Use of Radioautography in Investigating Protein Synthesis is a collection of papers that discusses the tracing of labeled proteins through photographic emulsion, particularly radioautography or autoradiography. The papers discuss proteins at the site of their synthesis, their subsequent migration through the cell, their secretions, and the formation of the basement lamella in salamanders. One paper outlines the primary aims in specimen preparation for electron microscope autoradiographic techniques and the procedures to achieve them. Another paper reports on migrating proteins (CNP) and nonmigrating proteins of the Amoeba proteus nucleus in which nonmigrating proteins are sedimentable by centrifugation in situ in the nucleus. One paper investigates the extent of protein synthesis for cell renewal in thoracic duct lymphocytes (TDL) or that for export or intracellular turnover. The protein synthesized by the large cell population in TDL is associated with mitosis and cell renewal. A major portion of that synthesized by the medium cells (80 per cent) and practically all of that produced by small cells are for purposes other than cell renewal. The collection can prove beneficial to biochemists, micro-biologists, bio-physicists, cytologists, histologists, pathologists, cellular researchers, and academicians involved in the study of cellular biology.
