Effects of sTn or cTn treatment on Ca2+ sensitivity and t 1/2 in rabbit psoas muscle fibers. a Effect of sTn or cTn treatment on force–pCa curves (top) and passive force (bottom). Black solid lines control without sTn or cTn treatment (same as in Fig. 2), gray solid lines sTn treatment, green solid lines cTn treatment. Inset, ΔpCa50 with and without Tn treatment. C control with no Tn treatment. *P < 0.05; n = 5 and 11 for sTn and cTn treatment, respectively. b Comparison of t 1/2 in the absence and the presence of sTn or cTn treatment. See [8] for the measurement of t 1/2 with Tn treatment. *P < 0.05 compared with control, NS not significant; n = 5 and 11 for sTn and cTn treatment, respectively
