title: The relationship between pH and the amount of calcium bound to glycerinated muscle fibers.
abstract: Variation of pH over the range 6.2--7.4 had no effect on the Ca2+ titration curve of glycerinated rabbit psoas muscle fibers. Thus the effect of H+ on muscle contraction is not due to a simple H+-Ca2+ competition for binding sites.
