1. 1. Conditions for in vitro translation of mRNA in cell-free extracts from cultured Spodoptera frugiperda cells were defined. 2. 2. Incorporation of [35S]methionine into acid-precipitable material increased for approximately 1 hr, and was sensitive to the protein synthesis inhibitors pactamycin and cycloheximide. 3. 3. Micrococcal nuclease-treated lysate, primed with purified rabbit globin mRNA, synthesized a major protein with the size of full length globin, indicating that the lysate supported correct initiation and elongation of polypeptides.
