Title:
METHOD FOR PRODUCING PARVOVIRUS HAVING HIGH INFECTIVITY TITER
Document Type and Number:
WIPO Patent Application WO/2014/080676
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing a parvovirus having a high infectivity titer in a stable and simple manner. The problem can be solved by a method for producing a parvovirus having an infectivity titer as high as 108 TCID50/mL or more in a culture supernatant, said method comprising the steps of: inoculating a culture base material, which comprises a host cell at a cell density of 1/500 to 1/20 of the cell density achieved upon the proliferation of the host cell to confluent and a culture medium, with a seed virus of the parvovirus so that the multiplicity of infection becomes 0.0001 to 0.1; culturing the seed virus and the host cell for a time that is 5 to 11 times the doubling time of the host cell; and then collecting the culture supernatant.
