Biological experiment method (protocol/SOP) search, comparison, and structured retrieval for synthetic biology and drug discovery labs. Use when the user asks to: find an experimental method or SOP (LC-MS, fermentation, protein expression/purification, enzyme assay, molecular cloning, etc.), compare protocols, look up troubleshooting for a lab method, retrieve step-by-step parameters for a known SOP, search PubMed/Europe PMC/protocols.io for method literature, generate a grounded SOP draft, or check protocol completeness. Supports Chinese and English queries. Enforces compliance: internal full-text is returned; external sources return metadata + abstract + link only.
