Comparative characterization of monoclonal antibodies to carbonic anhydrase.

Monoclonal antibodies (Mabs) were generated to avian carbonic anhydrase-C and characterized; their reactivity with human, murine, bovine, chicken and fish erythrocyte carbonic anhydrase-C, and with human carbonic anhydrase-B was investigated by ELISA and electroblot techniques. Reactivity of the Mabs with native and SDS-denatured carbonic anhydrase was compared. Mabs that recognize antigenic determinants shared by all the carbonic anhydrases examined were identified. The results demonstrate the potential usefulness of these particular probes for investigating various aspects of function, evolution, development and regulation of this important, but not well understood group of enzymes.
