This paper presents comprehensive protocols for rat and mouse kidney, heart, liver, lung, and pores and skin tissue lyophilization, human peritoneal dialysis (PD) fluid concentration, as well as water and solvent removal from human fecal samples. We analyzed whether freeze-dried tissue samples could be saved at 4 °C for 20 months or more without having high-quality impairment of RNAs and proteins.
The ultimate freezing process is impacted by the sort and amount of ice crystals produced on the determined cooling amount. The sort, dimensions, and amount of these ice crystals establish how the merchandise will freeze dry.
