Rodent biospecimens are used to gain a better understanding of a compound's pharmacokinetic properties. Charles River can provide blood products, tissues and organs collected from VAF/Plus® rats, mice, guinea pigs, hamsters or gerbils upon request. All biospecimens are collected in our biosecure surgery suite by experienced animal surgeons and processed in our surgical facilities by highly trained surgical technicians.

Each order is priced individually based on strain of research animal and the complexity of the procedure.
