摘要:
This invention relates to compositions and methods of preparing stable adjuvant diluent stock solutions and final adjuvant solutions comprising glycolipids, weak acids, alcohols, nonionic surfactants and buffers.
摘要:
The present invention provides a novel method that can increase readily a virus or viral vector concentration in a solution having a low concentration and a kit for performing the method. Conventional methods require complicated operations, expensive equipment, or highly trained experts for efficiently concentrating viruses from low-concentration virus solutions. The method of the present invention can concentrate viral vectors readily while maintaining infection abilities of the viral vectors, and thus it can be used as a safe and simple technique for concentrating a vector useful in the field of a genetic therapy or a vaccine therapy using a viral vector.
摘要:
Infectious laryngotracheitis virus (ILTV) and egg drop syndrome virus (EDS) production are currently cultivated in either primary cell cultures or in chicken embryos. These production practices are both costly and difficult. Until now no continuous cell line has been identified which is capable of supporting either ILTV or EDS replication. This invention involves the discovery that a chemically transformed chicken hepatocyte derived cell line is capable of efficiently supporting replication of both ILTV and EDS. Titers of virus harvested from cell culture are sufficient to allow conversion of production from chicken embryo or primary cell culture to continuous cell culture methods.
摘要:
The present invention relates to virus growth media that improve the yield of alpha-herpesviruses (e.g., HSV-2) grown in cell cultures. The growth media of the invention include two additives, a disaccharide and a lipid mixture, that can be added to serum-free or serum-enriched growth media to improve the efficiency of virus production. The invention further provides methods of producing alpha-herpesviruses (e.g., HSV-2) in such growth media.
