Quantitative analysis of short-term aggregation assays. This table lists the percentage of Cx- and mock-transfected C6 cells that form aggregates in suspension assay. Dye transfer assays ofGoldberg et al. (1995) were used as described in Materials and Methods. All assays were performed in a minimum of three independent runs (range, 3–16; mean, 9).
↵* , Significantly different from C6-Cx43 cells (p < 0.05). ANOVA for group comparison with post hoc t test is used to establish significant difference between the groups. All numbers indicate ± SEM.
