Electrophysiological analysis of Cx43 gap junctions.
A, examples of junctional current traces for Cx43 (Cx43-WT), Cx43W78L (Cx43stp), and Cx43P191S (Cx43sof) shown below voltage protocol (top). B, normalized junctional conductance of mutants compared with Cx43-WT. NC, negative control (only antisense oligonucleotide for Xenopus cx38 was injected). Error bars, S.E. **, p < 0.01.
