Sense and sensibility: Synthetic oligonucleotide receptors have been generated that are capable of discriminating proteins with as little as four amino acids substitutions. This leads to the possibility that a panel of cross-reactive aptamers can be an effective tool for discriminating proteins that are structurally similar without the need to generate a unique receptor for each variant.
