Figure 4. TEA sensitivity of XShal-induced current in oocytes. The current is efficiently blocked by TEA, in particular in the presence of
oocyte buffer. In the presence of the standard solution, which contains
10 mM cobalt and 5 mM magnesium, TEA sensitivity is reduced at low
concentrations (1 and 1.5 mr+r) but not at higher concentrations (15 and
40 mM). The sensitivities of the XSha2-induced current in oocytes as
well as the endogenous delayed-rectifier (ZKv) and A currents (Z,) to 40
rnr+r TEA in standard solution are also shown. Data for the endogenous
currents are obtained either from Rihera and Spitzer (1990) or from S.
M. Jones and A. B. Ribera (unpublished observations). Data are presenteda
sm eanf SEM for three to eight oocyteso r neurons. Image published in: Ribera AB and Nguyen DA (1993) Copyright © 1993.
