- Cell culture-based assay of parvovirus B19 and the relevance of animal model virusesJ Blumel
Paul Ehrlich lnstitut, Langen, Germany
Dev Biol (Basel) 118:107-12. 2004..The understanding of the mechanism underlying virus inactivation/removal might be helpful for the selection of model viruses and for the assessment of validation data on its relevance for a specific virus in question...
- Structure of simian virus 40 DNA replicated by herpes simplex virus type 1J Blumel
Institut fur Medizinische Mikrobiologie und Immunologie, Universitat Bonn, Sigmund Freud Strasse 25, Bonn, D 53127, Germany
Virology 276:445-54. 2000..This indicates that initiation of DNA synthesis on HSV-ori determines some, yet undefined, property of replicating HSV DNA, which is crucial for regular processing of the replication intermediates to daughter genomes...
