RESUMO
Subcellular membrane fractions were prepared from the salt glands of osmotically-stressed ducklings. Two fractions were characterized biochemically with respect to (Na+ + K+)-ATPase, alkaline phosphodiesterase I, succinate dehydrogenase, esterase, and galactosyltransferase activities and immunochemically with respect to (Na+ + K+)-ATPase. The ratios of the estimates of the (Na+ + K+)-ATPase contents obtained biochemically and immunochemically from the two fractions differed by more than 2 X. The results are consistent with the presence of at least two molecular species of (Na+ + K+)-ATPase, unevenly distributed between the two fractions.
