Table 1.

Ca²⁺ conductance and charge movement properties recorded from primary dysgenic myotubes and from the dysgenic cell line GLT are highly comparable

Data are given as mean ± SEM (numbers in parentheses are the myotubes tested). Recordings from primary dysgenic myotubes (cDNA injected) are indicated in italic and from immortalized dysgenic GLT myotubes (cDNA transfected) in roman. G_max is the maximal Ca²⁺ conductance (currents fitted according to ref. 24), Q_max is the maximum immobilization-resistant charge movement (Q_on fitted according to ref. 24), and Q′_max is the difference between Q_max and the average, endogenous charge movement Q_dys(max) found in dysgenic myotubes (Q_dys(max) = 2.5 nC/μF; ref. 24). Brackets indicate a lack of significant difference (P > 0.05) between data sets compared by an unpaired two-sample t test. Values for GFP-α_IS recorded from primary dysgenic myotubes were listed for comparison and were published (9).
