The invention discloses a recombinant bovine peginterferon α, a fusion protein for preparing the peginterferon and a preparation method thereof. The fusion protein is formed by connecting bovine interferon γ and bovine interferon α through a flexible linker, and the fusion protein is connected with bovine interferon α. After the lyoprotectant is mixed, the recombinant bovine peginterferon α can be obtained by lyophilization. The recombinant bovine long-acting interferon alpha can significantly increase the half-life of bovine interferon, which is more than 11 times higher than that of common bovine interferon, has broad-spectrum antiviral effect and can improve the immune response of cattle itself.

The invention discloses a fusion protein composed of ovine albumin and ovine interferon gamma, a preparation method thereof and a recombinant ovine long-acting interferon gamma. The fusion protein is composed of ovine albumin and ovine interferon gamma through a flexible linker The recombinant sheep peginterferon gamma can be obtained after mixing the fusion protein with the freeze-drying protective agent and freeze-drying. The recombinant sheep long-acting interferon gamma can significantly increase the half-life of sheep interferon, which is more than 12 times higher than that of ordinary sheep interferon gamma, has broad-spectrum antiviral effect and can improve the immune response of sheep itself.

The invention relates to broad-spectrum antiviral bactericidal plastic and application thereof. The bactericidal plastic is prepared from following components in percentage by weight: 90-96% of basicresin, 1-3% of a modified antibacterial agent, and 0-10% of a plastic additive, wherein the modified antibacterial agent is prepared from the following components in parts by weight: 5 to 15 parts ofchlorophyll, 5 to 15 parts of tea polyphenol, 8 to 16 parts of taurine, 0.5 to 2 parts of citric acid, 6 to 18 parts of isomalto-oligosaccharide, 0.6 to 1.5 parts of yeast powder, 4 to 10 parts of chitosan, 30 to 50 parts of nano titanium dioxide, 3 to 8 parts of zinc oxide and 3 to 8 parts of ultraviolet fluorescent powder. The broad-spectrum antiviral bactericidal plastic has a broad-spectrum antiviral effect, can kill viruses and bacteria for a long time, effectively prevents virus infection possibly caused by frequent contact between users and plastic cards such as bank cards and identitycards, and is beneficial to the health of the users.

The invention discloses a recombinant canine peginterferon, a fusion protein for preparing the peginterferon and a preparation method thereof. The fusion protein is formed by connecting canine interleukin 2 and canine interferon α through a flexible linker. The recombinant canine peginterferon can be obtained after the protein is mixed with the freeze-drying protective agent and freeze-dried. The recombinant canine peginterferon can significantly increase the half-life of canine interferon, which is more than 10 times higher than that of ordinary canine interferon, has broad-spectrum antiviral effect and can improve the immune response of canine itself.

The invention discloses a fusion protein composed of chicken albumin, chicken interferon gamma and chicken interleukin 2 and a preparation method thereof. The fusion protein is composed of chicken albumin, chicken interferon gamma and chicken interleukin 2. Formed by flexible linker connection, the fusion protein is mixed with a lyoprotectant and freeze-dried to obtain the recombinant chicken peginterferon. The recombinant chicken long-acting interferon can significantly increase the half-life of chicken interferon, which is more than 21 times higher than that of common chicken interferon, has broad-spectrum antiviral effect and can improve the immune response of chicken itself.

The invention discloses a fusion protein composed of ovine albumin, ovine interferon γ and ovine interferon τ and a preparation method thereof. The fusion protein is composed of ovine albumin, ovine interferon γ and ovine interferon τ through a flexible linker The recombinant sheep peginterferon can be obtained by lyophilizing after the fusion protein is mixed with the lyoprotectant. The recombinant sheep long-acting interferon can significantly increase the half-life of sheep interferon, which is more than 17 times higher than that of ordinary sheep interferon, has broad-spectrum antiviral effect and can improve the immune response of sheep itself.

The invention discloses recombinant ovine pegylated interferon tau, fusion protein for preparing the same and a preparation method of the fusion protein. The fusion protein is formed by connecting sheep interferon gamma and sheep interferon tau through a flexible linker, and the recombinant sheep pegylated interferon tau can be obtained from the fusion protein and a freeze-drying protective agent through mixing and freeze-drying. The recombinant sheep pegylated interferon tau can significantly prolong the half-life of the sheep interferon, the half-life is prolonged 10 times or higher compared with that of normal sheep interferon, and the recombinant sheep pegylated interferon tau has a broad-spectrum antiviral effect and can improve immune response of sheep.
