Protocol Online: Your Lab's Reference Book

Protocol Online is a pioneering, community-driven website and protocol portal founded in 1999 by Dr. Long-Cheng Li to facilitate scientific knowledge sharing across life sciences disciplines. Functioning as a collaborative digital reference manual, the platform curates, organizes, and indexes thousands of experimental protocols, laboratory techniques, and procedural recipes contributed by researchers, academic laboratories, and biotechnology institutions worldwide. The portal covers a broad spectrum of research domains, including molecular biology, cell biology, biochemistry, genetics, immunology, neuroscience, plant biology, developmental biology, and bioinformatics. Each listed entry provides step-by-step experimental procedures, buffer formulations, troubleshooting notes, and links to primary methodology literature. Beyond its core protocol database, Protocol Online hosts BioForum, an active discipline-specific discussion board where researchers exchange practical laboratory advice, troubleshoot technical setbacks, and discuss methodological refinements. As an essential open educational resource, this portal offers accessible experimental frameworks, hands-on lab manuals, and peer-supported technical guidance for undergraduate and postgraduate students, laboratory technicians, molecular biologists, and research scientists engaged in empirical life science research and experimental design.
