  • Publication number: 20240033346
    Abstract: Provided are a vaccine composition for Varicella Zoster virus (VZV) including a glycoprotein E (gE) antigen of VZV and monophosphoryl lipid A (MLA), and a method of using the same. The vaccine composition according to an aspect of the invention may significantly improve a production yield by including the gE antigen having an optimized signal peptide sequence, may enhance immunogenicity by including MLA, and may further enhance the immunogenicity enhanced by MLA by further adding saponin such as QS-21, and may be prepared in a form of CoPoP liposomes so that vaccine antigens may be presented on the surface of the liposomes for better absorption by antigen-presenting cells, and vaccine efficacy may be maximized by inclusion of the vaccine antigens and immune adjuvants in a formulation. Therefore, the vaccine composition may be useful as an alternative to current vaccines in the art for prevention or treatment of VZV infection.

  • Publication number: 20190376979
    Abstract: The present invention relates to a method for constructing an Fv library based on a combination of proteins, a method of screening a desired antibody using the constructed Fv library, an Fv antibody screened by the screening method, and an Fv library constructed by the Fv library construction method. The Fv library of the present invention is based on a combination of proteins so that members thereof can be individually analyzed for their function. Moreover, the Fv library enables a desired Fv antibody to be screened without needing a target antigen preparation. In addition, the protein combination based Fv library makes it possible to significantly reduce the number of protein purification processes to thereby reduce costs and time, compared to conventional DNA-based libraries.

  • Publication number: 20190077846
    Abstract: The present invention relates to a self-cleaving fusion protein including a target protein, a peptide consisting of amino acid sequence represented by LPXTG, a domain of Sortase A having cleaving function, and a tag, which are sequentially positioned from the amino terminal; a nucleic acid encoding the same; an expression vector including the nucleic acid of the present invention; and a cell transformed with the expression vector of the present invention. In addition, the present invention relates to a method for refining a target protein including culturing, dissolving, and purifying the transformed cell, and a method for preparing a therapeutic antibody-drug conjugate by using the purifying method.
