Antibodies as chiral selectors for the determination of enantioenrichment.

Stereoselective antibodies are excellent chiral selectors for the routine analysis of enantiopurity in, e.g., enzyme-linked immunosorbent assays and immunosensors. Here, we describe the application of stereoselective, group-specific antibodies to alpha-amino acids as tailor-made chiral selectors. The feasibility of chiral immunosensor techniques in space missions using these or other, newly designed antibodies is discussed.
