The CBCS is a coordinated research infrastructure distributed across six Swedish Universities. All nodes provide expertise in chemical biology to academic groups across Sweden. The KI and Umeå University nodes are the main screening nodes with both assay development and screening capabilities, along with enabling chemistry labs. CBCS Compound Center is located at KI. The nodes at Lund, Uppsala, Linköping and Gothenburg universities serve as access nodes, providing local assistance in assay development guidance. In addition, the local nodes also offer complementary capabilities and services, as described below.
