A method of determining the sequence of monomers which is a conformational equivalent of an epitope which is complementary to a particular paratope of an antibody of interest, the method comprising the steps of: 1. synthesizing a plurality of catamer preparations; each of said catamer preparations consisting of a plurality of catamers in which the composition at one or more designated positions in each catamer is known, and the composition at the remaining positions is randomly made up from members of a defined set of monomers; and said plurality of catamer preparations comprising preparations in which the composition at the designated positions is systematically varied to contain members from a defined set of monomers; 2. contacting each of the plurality of catamer preparations with the antibody of interest; and 3. detecting the presence or absence of binding between each of said plurality of catamer preparations and said given antibody to indicate a partial sequence of the mimotopes for the paratope of the said given antibody.

Method for determining mimotopes

A method of detecting or determining a sequence of amino acids which is antigenically active within a known amino acid sequence of a protein or portion thereof comprises the steps of: synthesising a plurality of peptides, each of said peptides comprising a sequence of a plurality of amino acids which corresponds to a sequence within the known amino acid sequence, and the said peptides having overlapping amino acid sequences; contacting each of said peptides with antibody against the protein or portion of interest; and detecting or determining the presence or absence of an antigen-antibody reaction between each of said peptides and said antibody to indicate whether or not said peptide has antigenic activity.

Method of determining antigenically active amino acid sequences

A method of detecting or determining the sequence of monomers which is a topological equivalent of the epitope which is complementary to a particular paratope of an antibody of interest, comprises the steps of: 1) synthesizing a plurality of catamer preparations; each of the catamer preparations consisting of a plurality of catamers in which the composition at one or more designated positions in each catamer is known, and the composition at the remaining positions is randomly made up from members of a defined set of monomers; and the plurality of catamer preparations comprises preparations in which the composition at the designated positions is systematically varied to contain members from a defined set of monomers; 2) contacting each of the plurality of catamer preparations with the antibody of interest; and 3) detecting or determining the presence or absence of binding between each of the plurality of catamer preparations and the given antibody to indicate a partial sequence of the mimotopes for the paratope of the given antibody.
