Toxicology and Safety

SRI offers mammalian toxicology testing services, in all major species, that follow either routine or customized study designs. Our expertise spans a wide range of pharmaceutical and therapeutic agents, including anticancer drugs, anti-infectives, vaccines, antisense therapeutics, nucleosides, peptides, antibodies, and proteins. We also offer testing of genetically engineered products and medical devices, such as combination 510(k) products, using protocols designed to meet your needs.
