Process for the identification or assay of a particular polypeptide antigen X in which an immunological determination of the presence of said polypeptide antigen X is carried out in a sample, characterized in that the sample is treated in vitro using at least one chemical reagent reacting

Process for the identification or immunoassay of polypeptide antigens

Process for the identification or determination of proteins by producing antibodies with the aid of peptides that are made immunogenic if necessary, and then using the resulting antibodies to determine the proteins of interest, starting with a sample that contains these and which is treated to liberate the said peptides, in which process the said peptide is so chosen that it matches a known amino acid sequence of the said protein and is used as a protein fragment that the protein can be made to release on enzymatic treatment, after which it is synthesized, the invention also relating to the applications of this process for the identification or the determination of proteins.
