title: Paralog chromatography.
abstract: As a mixed mode ligand, a small peptide can mimic an antibody's paratope (antigen recognition site). This report describes the construction of a representative set of paratope analogs, or "paralogs," which can be conjugated to a chromatographic sorbent to combine desirable characteristics of traditional high-performance liquid chromatography columns with the specificity of a moderate affinity antibody. The broad utility of this novel set of protein separatory reagents is illustrated on the complex mixture of proteins in a yeast lysate.
