title: The effect of carbon dioxide on the unidirectional transport of calcium in the isolated shell gland.
abstract: An in vitro technique was developed whereby the carbon dioxide (CO2) tension of the buffer bathing the isolated shell gland could be altered without changing the pH. The isolated shell gland tissue showed a steady and linear transport of calcium. When the CO2 tension of the buffer bathing the serosal side of the shell gland tissue was increased, there was approximately an 80% enhancement (P less than .05) of the unidirectional flux of 45Ca from serosal to mucosal surfaces.
