Abstract: The fluorescent probe Fura-2/AM was used to determine cytosolic free calcium concentration in soleus muscle and in isolated flexor digitorum brevis fibres. This required a precise calibration; therefore, each calibration parameter was studied in situ. The influence of the dye concentration on calcium measurements was also examined. This precise calibration technique was used to compare absolute free calcium concentration in resting preparations from dystrophic (mdx) and control (C57) mice. We showed that the behavior of the dye was not similar in C57 and in mdx muscles. For this reason, we did not confirm the previous results that cytosolic free calcium concentration is increased in mdx muscles.
