at pH 6.5, 7.3, and 8.0 are summarized in Fig. 1. Intermediate results were seen at pH 7.0 and 7.6 (not shown). Immediately after the pH manipulation, the b-crosslaps increased 0.2–6.6% (P .0.05). After 2 days, all samples exhibited a significant decrease of the b-crosslaps concentrations. In the control samples, b-crosslaps decreased by 12% at 37 °C and by 5% at room temperature on the second ...
