摘要
We cloned five new subtypes of cDNA encoding canine interferon-a (CaIFN-alpha) from a canine epithelial cell line. CaIFN-alpha s were divided into two groups by amino acid sequences and a molecular phylogenic tree. Two subtypes of them were expressed in Escherichia coli, and IFN proteins were purified. Recombinant CaIFN-alpha s were highly species-specific and showed antiviral activity against Vesicular stomatitis New Jersey virus and canine adenovirus-1, but not against canine herpesvirus-1.
