Claim One:
1. A method of determining at least one discriminant protein useful for identifying an individual, the method comprising: obtaining a plurality of samples, each sample comprising individual specific antibodies; contacting each of the plurality of samples with an array comprising a plurality of proteins to form at least one immune complex comprising an individual specific antibody from the sample bound to a protein of the array, wherein each protein is known and wherein each protein is immobilized at a known predetermined location in the array; applying at least one detection agent to the array, the detection agent comprising at least one interacting protein conjugated to a marker to detect the immune complexes; detecting the immune complexes on the array, to obtain an antibody profile corresponding to each of the different individuals; and comparing the antibody profiles corresponding to the different individuals to determine at least one target antigen as a discriminant protein useful for indentifying an individual.
