Incorporation of radioactive amino acids into proteins of the microsome fraction of guinea-pig liver in a cell-free system.

Although the synthesis of specific soluble proteins has rarely, if ever, been unequivocally demonstrated to occur in cell-free preparations of mammalian cells, the capacity for the uptake of amino acids into peptide linkage in 'non-specific' protein is less readily destroyed by damage to the cell. Thus the incorporation of labelled amino acids into the acid… (More)
