a cell-free protein synthesis system derived from ehrlich ascites tumor cell ribosomes ( s30 ) plus rabbit reticulocyte trna was developed and the activity of the system was dependent on rabbit reticulocyte ribosomal salt ( 0.5 m kc1 ) wash factors , the exogenous mrnas from balb/c mouse liver and the mammary gland were translated with a high efficiency in this heterologous cell-free system .
