U.V. Enhanced Reactivation of U.V.- and γ-irradiated Adenovirus in Normal Human Fibroblasts

An enhanced reactivation (UVER) of U.V.-irradiated as well as of gamma-irradiated human adenovirus type 2 (Ad 2) was detected following infection of normal human fibroblasts which had been pre-irradiated with U.V. light. U.V.-irradiated or non-irradiated fibroblasts were infected with either non-irradiated or irradiated Ad 2, and at 48 hours after infection cells were examined for the presence of viral structural antigens (Vag) using …
