  • Patent number: 5817468
    Abstract: 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 reactingon an epsilon -NH.sub.2 function of a lysine residue oron a terminal alpha -NH.sub.2 function of a peptidein order to carry out the linking of said reagent to said polypeptide antigen X and in this way to obtain a modified polypeptide antigen X, (polypeptide antigen Xm), the immunological determination of the presence of said polypeptide antigen X in said sample is then carried out using at least one antibody produced by immunization against a polypeptide antigen Y identical to the polypeptide antigen Xm or to an antigenic fragment of this antigen Xm.

  • Patent number: 5449601
    Abstract: 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.
