Sodium and Potassium Binding by Microsomes from Nasal Salt Gland,Harder's Gland,Kidney and Liver of Sea Gull. ∗

Summary

Microsomes from the nasal salt gland, liver and kidney were capable of binding Na⁺ and K⁺ at a level of 1.1–1.6 meq/g N. Microsomes from Harder's gland exhibited a Na⁺ and K⁺ binding of 2.3–2.5 meq/g N, which possibly represents binding to a mucopolysaccharide low in nitrogen. The high efficiency of the nasal salt gland could be associated with the elution-type mechanism of ion transport.
