    Abstract: A method of cross-linking a peptide to form a homopolymer of the peptide, to immobilize the peptide on a solid phase and to enhance antigenicity of the peptide is disclosed. The method comprises the steps of preparing a fusion peptide by incorporating a cross-linking segment including a tetrapeptide sequence Q-X-K-(S/T) (SEQ ID NO: 15) into the peptide and cross-linking the peptide by a glutaminase.

    Abstract: The present invention provides a method utilizing mammalian expression system for generating virus-like particles (VLPs) of mammalian-hosted viruses, particularly SARS-CoV. The method of the present invention involves expression of viral structural proteins in Vero cells and thereby obtaining recombinant VLPs in the culture medium. SARS-VLPs generated by the method of the present invention are highly immunogenic and can elicit not only humoral but also cellular immune responses in a mammal.

    Abstract: A novel anti-polyethylene glycol monoclonal antibody and its preparation are disclosed. Such an antibody can be used for determining polyethylene glycol concentration in vitro or accelerating the clearance of a polyethylene glycol containing compound from the blood circulation in the human body thereby reducing the toxicity associated with the polyethylene glycol containing conjugate. The antibody is particularly useful in cancer therapy where the therapeutic agent is selectively delivered to the tumor by increasing the tumor/blood ratio of the polyethylene glycol containing compound.
