Immunosignature (IMAGE) Arizona State University Caption To generate an immunosignature, an array of 10,000 short peptides on a chip is used. Each one is about twenty amino acids long, to generate a high degree of specificity and sensitivity for measuring both human, dog, and mouse infections and chronic and genetic diseases. A subset of these peptides will stand out, based on an individual's antibody repertoire, and provide a unique pattern, or signature for a given disease.
