1. A method to identify a peptide having a sequence of 4-20 amino acids useful for the conduct of affinity chromatography with respect to an analyte,wherein said peptide has specific affinity for said analyte, which method comprises:
- screening, for ability to bind said analyte, a panel of individual candidate peptides wherein said candidate peptides have systematically varied values of at least two parameters selected from the group consisting of hydrophobic index, amphipathic characteristics, and charge pattern.

Abstract
A method for affinity chromatography or adsorption of a designated analyte utilizes a paralog as the affinity partner. The immobilized paralog can be used in purification or analysis of the analyte; the paralog can also be used as a substitute for antibody in an immunoassay. The paralog is identified by screening candidate peptide sequences of 4-20 amino acids for specific affinity to the analyte.
