ABSTRACT:
A channel protein having a Na.sup.+ /K.sup.+ selectivity of approximately 100 and capable of affecting Na.sup.+ membrane transport is disclosed. Amiloride derivatives, and amiloride gel materials incorporating such derivatives, useful in treating membrane transport, cellular volume and cellular pressure disorders and in isolating the channel protein are also disclosed. These amiloride derivatives may be prepared by mixing the amiloride with an alkanediol in the presence of a base followed by addition of an acid. Use of the channel protein in diagnostic assays and screening assays is described.
