Fig. 10. 4-Chloro-  m -cresol (4-CmC) dose response. Normal (•) and MH (○) pig lymphocytes in suspension bathed in Ca²⁺-free Hanks balanced salt solution. Peak fura-2 ratios minus baseline values were normalized to the peak value for that curve and fit as described in Materials and Methods.  Data points with  error bars are means ± SEMs; n = 1–9 for each concentration.
