| Abstract: | Abstract. 8-Methoxypsoralen-sensitized photoinactivation of bacteriophage lambda (Λvir) was examined in the presence of various metallic ions. Paramagnetic ions, Co2+, Ni2+ or Mn2+, strongly repressed the reaction, whereas diamagnetic ions, Ca2+ or Zn2+, exerted no influence. Significant repression was also observed in the sample solution equilibrated with air. |
