摘要:
The present invention is directed at a composition comprising a live swine flu virus having an infectious component and a plurality of surface antigens in contact with a formaldehyde donor agent having a molecular weight that is less than about 400 g/mol. Preferably, the formaldehyde donor agent is selected from a non-crosslinking chemical fixative that contains urea.

Provided are a HCV particle formation promoter capable of promoting formation of HCV particles in culture cells, and a method of enhancing production of HCV particles. Also provided are a method of evaluating an anti-HCV agent candidate substance, and a method of producing a HCV vaccine. The HCV particle formation promoter comprises as an active ingredient a statin or a pharmaceutically acceptable salt thereof. Addition of the statin or pharmaceutically acceptable salt thereof to HCV-infected culture cells can promote formation of infectious HCV particles and enhance production of the particles. In addition, an anti-HCV agent candidate substance is evaluated by culturing HCV-infected cells in the presence of the HCV particle formation promoter and the anti-HCV agent candidate substance. Further, a HCV vaccine is produced by using HCV particles produced by the method of enhancing production of HCV particles.

The present invention provides a method of operating a reprocessor that has a chamber for receiving items to be sterilized. The reprocessor is filled with water that has passed through a first and a second filter element that both comprise a filtration system. A liquid sterilant is generated by mixing the water with dry chemical reagents. The liquid sterilant is circulated through a fluid circulation system and the filtration system wherein a portion of the liquid sterilant is directed through a bypass conduit and another portion is directed through the first and second filter elements. After a predetermined exposure time, the reprocessor is drained. Then the reprocessor is filled with water for rinsing that has passed through the first and the second filter elements. The water for rinsing is heated prior to being introduced into the reprocessor.
摘要:
The present invention provides a method for conveniently producing a protein formulation with viruses being inactivated, without impairing the quality of the obtained protein formulation, characterized by including the step of exposing the protein formulation contaminated with the viruses to a 0.1-2M aqueous solution of arginine, an arginine derivative or a mixture thereof, the aqueous solution being adjusted to pH 3.5 to 5. The present invention also provides a virus inactivation method characterized by including the step of bringing a virus-containing object into contact with a 0.1-2M aqueous solution of arginine, a arginine derivative or a mixture thereof, the aqueous solution being adjusted to pH 3.5 to 5.
