Interfering efficacy of DI244 material after SXC. Virus titers of the interference assay (see Fig. 3). Tested material was DI244 material produced in shake flask at MODIP 1E− 2, SXC purified material (as shown in Fig. 5), produced material inactivated by UV irradiation for 24 min (inactivated material) or medium as negative control (NC). Inactivated DI244 material was required as a control for animal experiments (Fig. 7). The interference assay was performed in independent experiments (n = 3) using one DIP preparation for each tested material. Error bars indicate standard deviation
