| Abstract: | Our investigations indicate the existence of binding sites for [3H]SCH23390 on crude membrane preparations in the anterior and posterior gills of the Chinese crab, Eriocheir sinensis acclimated to freshwater (FW) or seawater (SW). Maximum specific binding in the posterior gills is always higher than in the anterior gills, independent of saline acclimation. Kd values are similar in the two regions, suggesting the same affinity of both types of gills for the ligand, either from FW or from SW crabs. |
