The Cl\n                    <jats:sup>-<\/jats:sup>\n                    equilibrium potential between the thyroid interstitium and the lumen calculated from the measured Cl\n                    <jats:sup>-<\/jats:sup>\n                    activities was higher than the directly measured intraluminal potential. These data indicate that Cl\n                    <jats:sup>-<\/jats:sup>\n                    is actively transported out of the follicular lumen in turtle thyroid gland.

Results obtained from the specific liquid ion-exchanger microelectrode studies correlate well with those obtained from previous radioautographic observations and chemical determinations.\n                  <\/jats:p>","DOI":"10.1073\/pnas.67.2.998","type":"journal-article","created":{"date-parts":[[2006,5,31]],"date-time":"2006-05-31T02:23:42Z","timestamp":1149042222000},"page":"998-1004","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":9,"title":["Chloride and Potassium Activities in Luminal Fluid of Turtle Thyroid Follicles as Determined by Selective Ion-Exchanger Microelectrodes"],"prefix":"10.1073","volume":"67","author":[{"given":"S.
