    摘要: The present invention relates to the field of virology. More precisely, the invention provides a method of determining the ability of a test compound to modulate the biological activity of a variant of a target protein, wherein said test compound is previously known to modulate the biological activity of said protein. This invention is useful to determine whether a drug candidate, such as anti-viral compounds (eg. against hepatitis C virus: NS5B, NS3), active against a target protein is active against a variant of said protein (eg. polymorphisms, genotypes or mutants).

    摘要: A packaging cell line that complements recombinant adenoviruses based on serotypes from subgroup B, preferably adenovirus type 35. The cell line is preferably derived from primary, diploid human cells that are transformed by adenovirus E1 sequences either operatively linked on one DNA molecule or located on two separate DNA molecules, the sequences being operatively linked to regulatory sequences enabling transcription and translation of encoded proteins. Also disclosed is a cell line derived from PER.C6 that expresses functional Ad35 E1B sequences. The Ad35-E1B sequences are driven by the E1B promoter or a heterologous promoter and terminated by a heterologous poly-adenylation signal. The cell lines are useful for producing recombinant adenoviruses designed for gene therapy and vaccination. The cell lines can also be used for producing human recombinant therapeutic proteins such as human growth factors and human antibodies. Also, the cell lines are useful for producing human viruses other than adenovirus such as influenza virus, herpes simplex virus, rotavirus, and measles virus.
