Capillary electrophoresis-systematic evolution of ligands by exponential enrichment (CE-SELEX) has previously been used to select aptamers for large-molecule targets such as proteins, lipopolysaccharides, and peptides. For the first time, we have performed CE-SELEX selection for a small-molecule target, N-methyl mesoporphyrin (NMM), with a molecular weight of only 580 g/mol. DNA aptamers with high-nanomolar to low-micromolar dissociation constants were achieved after only three rounds of selecti ...[more]
