Abstract:
Summary The mutation frequency of L5178Y mouse lymphoma cells to resistance to 5′-bromo-2′-deoxyuridine increased 6-to 14-fold after growth in ethylene oxide-sterilized polycarbonate culture flasks compared to growth in glass flasks. No comparable increase was observed when L5178Y cells were growth in identical polycarbonate culture flasks sterilized by autoclaving.
