Springer Science+Business Media has announced the release of Springer Protocols, a protocol database of more than 18,000 searchable online protocols in life sciences and biomedicine. The protocols provide step-by-step "recipes" that can be executed in a controlled laboratory environment. Springer Protocols is a subscription product published under the Humana Press imprint. Used primarily in the life sciences, protocols provide individual sets of instructions that allow scientists to recreate experiments in their own laboratory. These documents provide instructions for the design and implementation of experiments that include the safety bias, procedural equipment, statistical methods, reporting, and troubleshooting standards for the experiment. The Protocols are organized into 15 subject collections: Biochemistry, Bioinformatics, Biotechnology, Cancer Research, Cell Biology, Genetics/Genomics, Imaging/Radiology, Immunology, Infectious Diseases, Microbiology, Molecular Medicine, Neuroscience, Pharmacology/Toxicology, Plant Sciences, and Protein Science.
