Described is a method for identification, isolation and production of hyperimmune serum-reactive antigens from a specific pathogen, a tumor, an allergen or a tissue or host prone to auto-immunity, said antigens being suited for use in a vaccine for a given type of animal or for humans, which is characterized by the following steps: providing an antibody preparation, providing at least one expression library, identifying antigens which bind, screening the identified antigens, identifying the hyperimmune serum-reactive antigen portion of said identified antigens and which hyperimmune serum-reactive antigens bind to a relevant portion of said individual antibody optionally isolating said hyperimmune serum-reactive antigens and producing said hyperimmune serum-reactive antigens by chemical or recombinant methods.

Method for identification, isolation and production of antigens to a specific pathogen

Described is a method for identification, isolation and production of hyperimmune serum-reactive antigens from a specific pathogen, a tumor, an allergen or a tissue or host prone to autoimmunity, said antigens being suited for use in a vaccine for a given type of animal or for humans, which is characterized by the following steps:&#x2014;providing an antibody preparation from a plasma pool of said given type of animal or from a human plasma pool or individual sera with antibodies against said specific pathogen, tumor, allergen or tissue or host prone to auto-immunity,&#x2014;providing at least one expression library of said specific pathogen, tumor, allergen or tissue or host prone to auto-immunity,&#x2014;screening said at least one expression library with said antibody preparation,&#x2014;identifying antigens which bind in said screening to antibodies in said antibody preparation,&#x2014;screening the identified antigens with individual antibody preparations from individual sera from individuals with antibodies against said specific pathogen, tumor, allergen or tissue or host prone to auto-immunity,&#x2014;identifying the hyperimmune serum-reactive antigen portion of said identified antigens and which hyperimmune serum-reactive antigens bind to a relevant portion of said individual antibody preparations from said individual sera and&#x2014;optionally isolating said hyperimmune serum-reactive antigens and producing said hyperimmune serum-reactive antigens by chemical or recombinant methods.

Described is a method for isolating Hepatitis C Virus peptides (HPs) which have a binding capacity to a MHC/HLA molecule or a complex comprising said HCV-peptide and said MHC/HLA molecule characterized by the following steps: &#x2014;providing a pool of HCV-peptide, said pool containing HCV-peptides which bind to said MHC/HLA molecule and HCV-peptides which do not bind to said MHC/HLA molecule, &#x2014;contacting said MHC/HLA molecule with said pool of HCV-peptides whereby a HCV-peptide which has a binding capacity to said MHC/HLA molecule binds to said MHC/HLA molecule and a complex comprising said HCV-peptide and said MHC/HLA molecule is formed, &#x2014;detecting and optionally separating said complex from the HCV-peptide which do not bind to said MHC/HLA molecule and optionally isolating and characterizing the HCV-peptide from said complex.
