Figure 2

Complex stiffness (N/m) with standard errors (shown at alternating loading rates for each sample) for the means of the loading rates for control samples at 4°C (identified by open circles) and samples frozen to -20°C (identified by open triangles), -80°C (identified by open squares), or snap frozen in liquid nitrogen and stored at -80°C (identified by crosses). Plot A identifies the complex stiffness behaviour of samples immediately after thawing and plot B identifies the complex stiffness behaviour after 4 hours storage at 22°C. They both reveal no mean complex stiffness differences among the various storage temperatures.
