Cells were prepared as previously described [10,11] and used for virus titrations and hemadsorption tests. Both methods were carried out according to standard procedures [12]. For quantitative real-time PCR (qPCR),viral DNA was extracted using the QIAamp®DNA Mini Kit (QIAGEN)according to the manufacturer’s instructions. Subsequently, qPCRwas performed according to the protocol published by King et al.[13] using a Bio-Rad CFX Cycler (Bio-Rad Laboratories). A dilutionseries of a synthetic standard with known copy numbers was used to quantify genome copies in the respective samples. To confirmintegrity of the p73 antigen after inactivation, immunogen preparations were tested in the commercial antigen ELISA Ingezim PPADAS K2 (INGENASA) according to the manufacturer‘s instructions.Moreover, genome copy numbers were compared prior and afterinactivation.Sera were tested for the presence of ASFV p73- and p30-specific antibodies using the INGEZIM PPA COMPAC ELISA (Ingenasa)and the SVANOVIR ASFV-Ab (SVANOVA) according to the manufacturer’s instructions. To assess neutralizing capacities of sera obtained prior to challenge infection, macrophage infection inhibition assays were carried out along with neutralization tests on permanent wild boar lung cells (WSL). Hemadsorption inhibition and indirect immunofluorescence staining was used asreadout (methodological details are available from the authors upon request).
