This website from Open Culture provides links to free online biology courses from "the world's leading universities." Some courses can be downloaded, while others are available through the web. Courses include Anatomy & Physiology from Carnegie Mellon, Brain Structure and its Origins from Gerald...

Lia Kent, of Stemgent's Research and Development team, has created this video to demonstrate "the proper technique for rapidly thawing hES cells from liquid nitrogen stocks, plating them on mouse embryonic feeder cells, and slowly freezing them for long-term storage." The video is also accompanied...

This webinar, published by the Wake Forest University School of Medicine, includes three short presentations that connect practical aspects of regenerative medicine curriculum to the training of the future biotechnology workforce, followed by a panel discussion. In the first presentation, Jim...

The North Carolina Community College System BioNetwork's interactive eLearning tools (IETs) are reusable chunks of training that can be deployed in a variety of courses or training programs. IETs are designed to enhance, not replace hands-on training. Learners are able to enter a hands-on lab...

This video, distributed on YouTube by the Royal Society of Chemistry, is on the basic principles of Gas Chromatography. This video is a short primer which introduces the technique and instrumentation. There are many assumptions that are made in the presentation of this material, due to the fact the...

This site contains a brief introduction to the concepts of injection and detection in gas chromatography, focusing on the split/splitless injection port and flame ionization detectors. The treatment is similar to that in analytical chemistry textbooks, and includes detailed illustrations.

In the early days of DNA manipulation, DNA fragments were laboriously separated by gravity. In the 1970s, the powerful tool of DNA gel electrophoresis was developed. This process uses electricity to separate DNA fragments by size as they migrate through a gel matrix. This animation from Cold Spring...

This lab activity from the Biotechnology Alliance for Suncoast Biology Educators (BASBE) introduces the methods of RFLP analysis, or DNA fingerprinting, by using gel electrophoresis. Students will learn the role of restriction enzymes in DNA fingerprinting. Required materials, procedure and...

This lab activity from the Biotechnology Alliance for Suncoast Biology Educators (BASBE) provides instructions for conducting a gel electrophoresis lab. Students will try to solve a paternity case with this activity by obtaining a DNA fingerprint from each potential father, the mother and the child....

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with the lac operon. Build a gene network! The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial...
