Abstract
Conclusions
Serum heavily infected with a virus (bacteriophage T4r) was sterilized by a combined method of treatment which consisted of ultraviolet irradiation followed by the addition of beta propiolactone. The beta propiolactone in concentrations as low as 1.5 g per liter could be used effectively. Under these conditions there is no change in the serum proteins as determined by electrophoretic analyses. Under the conditions in this study, either ultraviolet irradiation or beta propiolactone individually did not sterilize the serum.
