[Protein biosynthesis in a cell-free protein synthesis system from nodular euthyroid goiter cells]

Analysis of proteins, synthesized in cell-free system using nodal euthyroid goiter, was carried out by polyacrylamide gel disc electrophoresis. Four protein farctions, incorporating labelled amino acids, were found: "complete" thyroglobulin, two its subunits and thyroalmbumin. This correlates with the concept that malignant cell synthesizes intensively proteins untypical for a normal tissue.
