Created for that Solutions in Pharmacology and Toxicology collection, chapters contain the type of specialist assistance that contributes to top-quality ends in the lab.
Protocols for lyophilization as well as their efficacy for several samples. Agent graphs and reference protocols with exact time, temperature, and strain values indicated for every period employed for: a kidney, coronary heart, liver, and lung tissue samples; b aorta and pores and skin tissue samples; c peritoneal dialysis fluid focus; d liquid removal from fecal samples.
