EAAT3 dependent release of [³H]-L-glutamate or [³⁵S]-L-cysteine.

<p><b>A and B)</b> Release of [³⁵S]-L-Cysteine (<b>A</b>) or [³H]-L-Glutamate (<b>B</b>) from oocytes co-expressing EAAT3 and ASCT, in response to different buffers and conditions <b>C)</b> Averaged current-voltage relationships recorded from oocytes expressing EAAT3 alone (n = 6) or co-expressed with ASCT1 (n = 4) in response to a family of voltage pulses in the absence (black symbols) and the presence of 1 mM serine (blue symbols) or 1 mM glutamate (red symbols). The solid line represents un-injected oocytes in the presence of 1 mM glutamate and 1 mM serine (n = 3).
