Abstract

A process for producing and purifying peptides and for producing peptide/protein antigens for antibody production is described. The process utilizes fusion proteins and specifically fusion proteins in which the fusion protein carrier segment includes an amino acid sequence at least about 65 amino acids long and in which the amino acid sequence does not contain negative or positive charged side chains of amino acids.
