Abstract:
Provided are a parvovirus derived from an unconcentrated cell culture supernatant, having a infectivity titer of 109 TCID50/mL or more and an {infectivity titer (TCID50/mL)}:{impurity protein concentration (ng/mL)} ratio more than 5000:1; and a method of producing such a high-infectivity titer and high-purity parvovirus.
