Scope of Services

Drug screening services, novel drug R&D services, lead optimization, target screening, selection of preclinical candidates, etc.

Drug Screening Service Process
  1. Submit drug screening requirements: including sample type, basic properties, requirements for assay systems or cell lines, target selection, project timeline, acceptance criteria, and other screening-related requirements.
  2. Submit to the Drug Screening Center for comprehensive evaluation: submit the above requirements in the form of a project task sheet. Internal evaluation will be conducted based on assay system, workload, estimated timeline, associated costs, and other indicators. Supplementary materials will be requested if needed.
  3. Discuss project details: negotiate on subsequent R&D and other project-related matters according to mutual requirements.
  4. Finalize experimental protocol and sign contract/agreement: once the final protocol is confirmed, a binding cooperation agreement or contract will be signed in accordance with procedures.
  5. Execute project and summarize results in experimental report: complete the project on time as agreed, summarize experimental data and conclusions, and issue an official experimental report stamped with the official seal of the center or legal entity.
  6. Accept results and complete cooperation: both parties conduct acceptance, sign off, and finalize the cooperation.
