Statistical analysis
Data were analysed in Excel (Microsoft, USA) and compared using
one/two-way-ANOVA followed by Bonferroni-post-hoc-test (for
Gaussian-distributed samples) using Graphpad Prism (Graphpad Software,
USA). Error bars represent SEM. Significance was assumed with p ≤ 0.05.
Data are shown as mean ± SEM. Each n represents one independent
experiment.
