NH3/NH4+-independence of Gm in mSlc4a11-expressing oocytes. A: representative experiment showing progressive changes in Gm in an mSlc4a11-expressing oocyte exposed to pHe = 8.5 solution containing 5 mM NH4Cl at spontaneous Vm (black data points), or subsequently to NH3/NH4+-free pHe = 8.5 solution (white data points). Data points marked with * or # were generated from data similarly marked in B accompanying representative I–V plots and C accompanying current ladders. D: averaged data from six cells showing the influence of extracellular NH3/NH4+ removal on NH3/NH4+-induced Gm. Statistic is the result of a two-tailed, paired t-test.
