title: [Unmasking effect of trypsin on Sendai virions obtained in KB cell cultures (author's transl)].
abstract: The infectivity of virus grown in KB cell cultures can be directly activated by trypsin. Thus the fit conditions for seeding are effected from subculture to subculture if the cell inoculum is pretreated by trypsin.
