title: Lack of enhanced reactivation of simian virus 40 irradiated with van de Graaff electrons in U.V.-irradiated CV-1 monkey cells.
abstract: Simian virus 40 (SV40) irradiated with U.V. or van de Graaff electrons was assayed on CV-1 monkey cells irradiated with U.V. before virus infection. U.V.-irradiated cells enhanced the survival of U.V.-irradiated virus, while little or no enhancement was observed for electron-irradiated virus assayed on U.V.-irradiated cells. It is suggested that the U.V.-irradiated cells are able to increase the repair of U.V.-damaged viral DNA, but not of electron-damaged DNA.
