Nature Protocols "is an online journal of laboratory protocols for bench researchers. Protocols are presented in a 'recipe' style providing step-by-step descriptions of procedures which users can take to the lab and immediately apply in their own research. Protocols on the site are fully searchable and organized into logical categories to be easily accessible to researchers."
Protocol Online is a database of research protocols in a variety of life science fields. There are protocols from global researchers and links to bio techn companies, personal websites and other web protocols.
"The myExperiment Virtual Research Environment enables you and your colleagues to share digital items associated with your research — in particular it enables you to share and execute scientific workflows."
Online community for biology and bioengineering, featuring areas to share protocols, courses, and lab information.
Journal of Visualized Experiments (JoVE)
Check the Journal of Visualzed Experiments. This resource for videos on protocols. These protocols offer step-by-step instructions to enable others to reproduce the technique. Each video is 10-15 minutes long and is by a written component, which contains introductory remarks, the protocol, representative results, discussion, and references.
