The cytoplasmic isozymes of carbonic anhydrase in the gastrointestinal tract of reindeer

: The cytoplasmic isozymes of carbonic anhydrase: CA I and CA II, in the gastrointestinal tract tissues of reindeer were identified by electrophoresis and substrate-inhibitory tests. The study of the tissue distribution and composition of the cytoplasmic isozymes has shown, that isozyme CA II is found in the forestomachs and the colon mucosal tissue, whereas isozyme CA II predominates in the abomasum and small intestinal mucosa tissue.
