Fig 10. Dependence on the final pH of the fraction myosin denatured at rigor. Rates of pH fall 0.001, 0.005, 0.01, 0.02, 0.04 and 0.1 units/min as indicated above each curve. Initial and final pH, 7 and 5.5, respectively. Initial and final temperature, 39^oC and 4^oC, respectively.Half-cooling time 180 min.
