Semiquantification of the amounts and ratios of AQP2-S256A and AQP2-S256D-F in coinjections. Copy RNAs encoding AQP2-S256D-F and AQP2-S256A were mixed in the ratios 1:3, 1:2, 1:1, 2:1, and 3:1 (from left to right) and a total of 0. 4 ng was injected into oocytes. 2 d later, the Pf values were determined (see Table ) and total membranes were isolated and immunoblotted for AQP2. The individual signals of AQP2-S256A (SA) and AQP2-S256D-F (SD) were scanned and the amounts of expressed protein were semiquantified (in arbitrary units) using the scanned signals of a twofold dilution series of wt-AQP2 as a standard. From these data, the SD/SA ratio and total AQP2 amounts were calculated.
