Journal of Visualized Experiments 

A unique online-only journal that provides video-based demonstrations of biological techniques and procedures. Each video-article will include step-by-step instructions on an experiment, a demonstration of equipment and reagents, and a short discussion by experts describing possible technical problems and modifications.


This calculator from the National Institute of Standards and Technology allows researchers to enter output from a mass spec run and then specifies the location and size of the peaks. Input files must be simple ASCII text files of two columns - one for mass and one for ion intensity.

Microscopy and Imaging Resources 

Links to information on principles and techniques for several types of biological microscopies. From the Southwest Environmental Health Sciences Center, an NIEHS-funded center at the University of Arizona. 

Information resource on microscopes and microanalysis topics such as technical expertise and equipment evaluation, directories of laboratories and societies, glossary, training and short courses, resources for K-12 and a guide to online microscopy resources.

Molecular Expressions: Exploring the World of Optics and Microscopy 

Includes a primer on microscopy, but the site is noteworthy for its photo gallery of “photo-micro-graph” images  using an optical microscope. Also includes tutorials on various microscopic instruments (Olympus MIC-D, stereoscopic zoom).

Separations Now 

A “community of interest” web site for researchers involved in separation science and chromatography. Covers electrophoresis, gas and HPL chromatography, hyphenated techniques and genomics. Features include news, education training modules, discussion boards, organized links to other Web resources and conference information.
