Figure 4.
Normalized time response of lyophilized ST68 in 100 mM lyoprotectant solutions tested at 23°C (A) and 37°C (B) temperature. ANOVA testing showed ST68 with glucose at 23°C to be the only lyoprotected agent statistically greater than that of the ST68 control and all other lyoprotected samples after 15 minutes (*p<0.05, **p<0.01) (f = 5 MHz, 684 kPa, PRF = 100 Hz)
