Springer Nature Experiments is the world's largest database of laboratory research protocols, and comprises the popular monographic series Methods in Molecular Biology plus protocols gleaned from Methods in Molecular Medicine, Methods in Biotechnology, Methods in Pharmacology and Toxicology, and Neuromethods, as well as from a vast number of Laboratory Handbooks, such as The Biomethods Handbook, The Proteomics Handbook, and the Springer Laboratory Manuals. Researchers can browse the database by subject collection, search the database full-text, or follow a link to a protocol from other search engines like LionSearch or Google Scholar, or from a database such as PubMed or Web of Knowledge.
