Finally, the transapical voltage did not significantly respond to luminal pH changes induced either by perfusion with pH 10 or by stopping the luminal perfusion with unbuffered...

...H. Onken; S. B. Moffett; D. F. Moffett SUMMARY The lumen-negative transepithelial voltage ( V te ) of the isolated and perfused anterior stomach of mosquito larvae ( Aedes aegypti ) was studied with a `semi-open' preparation in which one end of the gut was ligated onto a perfusion pipette...

... perfused Malpighian tubules, the control transepithelial voltage ( V t ) was 19.4 mV (lumen-positive), and the transepithelial resistance ( R t ) was 6.37 kΩcm( Table 1 ). In principal cells studied by the methods of TEVC, the control basolateral membrane voltage( V bl ) was –75.2 mV, and the input...
