Figure 8
Biological activity of TRAIL and S-TRAIL over 4 weeks storage at 4 °C. The molar concentration of 25 and 50 µg/ml of TRAIL protein are equal to the molar concentration of 80 and 160 µg/ml of S-TRAIL, respectively. Statistical significance was evaluated by repeated ANOVA test and student t-Test. \(^{*}p < 0.05,\;^{**}p < 0.01,\;^{***}p < 0.001\).
