title: Specific monovalent cation effects on modification of reovirus infectivity by chymotrypsin digestion in vitro.
abstract: Specific monovalent cations control the modification of reovirus infectivity by chymotrypsin. Digestion in K(+), Rb(+), or Cs(+) reduces infectivity several logs, whereas in Na(+) or Li(+) digestion markedly enhances infectivity.
