Protocols for lyophilization and their efficacy for different samples. Agent graphs and reference protocols with correct time, temperature, and strain values indicated for every stage employed for: a kidney, heart, liver, and lung tissue samples; b aorta and pores and skin tissue samples; c peritoneal dialysis fluid concentration; d liquid elimination from fecal samples.
