A, B, C, D) % of the original Signal-to-noise/background ratio values over 24h for TdTomato in samples incubated in PBS (control), TDE 60%, 80%, 90%, and 100% plus additional post- incubation PBS wash for A) TdTomato and B) EGFP in heart samples, C) TdTomato and D) EGFP in liver samples. N=3. Error bars shown as standard error. E) Representative images of TdTomato (left, red) and EGFP (right, green) visualization in liver samples after 24h incubation in PBS, 60% TDE 80% TDE, 90% TDE and TDE 100%.
