摘要:
The invention relates to the discovery of an HEV strain from a chronically infected patient. The virus grow unusually well in numerous cell cultures. Thus, the invention provides cell cultures, vectors, and vaccine compositions based on the virus. The invention relates, in part, on the identification of a new strain of HEV genotype 3 virus. Strain Kernow-C1 (genotype 3) of HEV, which was isolated from a chronically infected patient, was used to identify human, pig and deer cell lines permissive for infection. Adaptation of the Kernow-C 1 strain to growth in human hepatoma cells selected for a rare virus recombinant that contained an insertion of 174 ribonucleotides (58 amino acids) of a human ribosomal protein gene and additional mutations.

Polybrene as an additive in cell culture medium is used in methods for the generation of high-titer hepatitis E virus stocks and assays for titration of hepatitis E virus. A cell culture medium containing polybrene is used for high-titer HEV generation, a method for determining the presence and/or the level of HEV in a sample, and an HEV titration assay using polybrene.
摘要:
A method of purification of non-enveloped or pseudo-enveloped virus produced in vitro uses a composition with at least one detergent. A method of purification can use multiple detergents, and a method of determining the presence and/or level of a non-enveloped or pseudo-enveloped virus in a sample includes treating with at least one detergent.
