Localization of human muscle carbonic anhydrase isozymes using immunofluorescence.

ABSTRACT

Human muscle sections were examined for the presence of carbonic anhydrase using fluorescent second antibody and antisera specific for the three isozymes, carbonic anhydrase I (CAI), carbonic anhydrase II (CAII), and carbonic anhydrase (CAIII). CAIII was present in all fibers, CAII only in the connective tissue, and CAI showed a weak association with the sarcolemma.
