Cyclic nucleotides in anatomical subdivisions of the bovine lens

Abstract
CAMP and cGMP were measured in whole and anatomically subdivided areas of bovine lenses. The highest values of cAMP and cGMP (2.843 pmol/mg protein and 0.0139 pmoles/mg protein, respectively) were found in the epithelium. The lowest values of cAMP and cGMP (0.007 pmol/mg protein and 0.001 pmol/mg protein, respectively) were detected in the central nucleus. Values for the cyclic nucleotides in the whole tissue more closely resembled those of the whole nucleus.
