Preclinical research in California

California has two of the largest biotech clusters in the United States: the San Francisco Bay Area, including South San Francisco, and San Diego. Many sponsors there are discovery-stage companies that outsource in vivo pharmacology, PK and early safety work.

Local in vivo capacity is valued for close collaboration during discovery, while larger IND-enabling packages are often placed with labs elsewhere in the US. The directory lists both, so compare by service and species as well as by location.
