  • Publication number: 20240082387
    Abstract: The present invention relates to a fusion protein comprising a SARS-CoV-2-derived receptor-binding domain and a nucleocapsid protein, and the use thereof. The fusion protein comprising a coronavirus-derived receptor-binding domain and a nucleocapsid protein is highly applicable to a multivalent vaccine composition having greatly improved in-vivo half-life and remarkably superior efficacy compared to an immunogenic composition comprising only a receptor-binding domain. In particular, the fusion protein can greatly improve the titer of the coronavirus-specific antibody formation and T-cell immune response, and is thus useful for the prevention and treatment of coronaviruses comprising SARS-CoV-2.

  • Publication number: 20220002922
    Abstract: The present invention relates to a method manufacturing a melt-spun nonwoven fabric and a microfiber nonwoven web manufactured therefrom The present invention relates to a method for manufacturing a melt-spun nonwoven fabric, in which fibers obtained by melt-spinning a thermoplastic polymer through a spinning nozzle including at least one nozzle hole are collected by high-speed air stream, wherein the melt-spun fibers are subjected to momentary local heating at a high temperature higher than a spinning temperature while same are caused to pass through a nozzle local heating provided directly under the spinning nozzle during spinning, so that the method can lower the melt flow index and spinline elongation viscosity of a thermoplastic resin discharged from the nozzle hole without reducing a molecular weight, thereby providing a microfiber nonwoven web formed by finely thin fibers, compared to the conventional spun-bond nonwoven fabric.
