Radio frequency inactivation of the enzymes chymotrypsin and alpha-amylase and living cells of the Mouse L-929 line were studied with variables of frequency, time, temperature, voltage, and pulse duty cycle. Inactivation times of the order of 1 minute were found for the living cells, and cell death was morphologically different from that caused by heat inactivation. Although in some experiments enzyme inactivation of up to 30 was observed on irradiation for times of the order of 10 hours, statistical analysis of the data did not indicate close correlation of enzyme inactivation with any of the variables tested.
