[Studies of differences in protein accretion in mice by means of cell-free protein synthesis systems].

A comparison of the stimulating activity of the muscle cell sap fraction of mice of the 0th, 4th and 6th generations selected according to the protein content in their carcasses in the cell-free ribosomal and polysomal protein synthesis systems showed that both systems are applicable to detect differences in accretion of protein. These differences ar much more distinct in the cell-free polysomal system than in the ribosomal poly(U) system.
