Want to teach your students about gel electrophoresis but don't have the time or resources? Why not use this durable, simulated gel? It closely imitates the look and feel of a real gel and can be used over and over again. Use it to teach how to create standard curves and calculate the molecular weight of DNA fragments—skills taught as part of AP® Biology Lab 6—or to practice gel loading. Simply wash the gel when you are finished. The model has 8 lanes total, 4 of them simulating the following digests: lambda cut with HindIII, lambda cut with EcoRI, and lambda cut with both EcoRI and HindIII (there are 2 lanes of this digest).
