Mouse Party

In this interactive activity from The University of Utah, examine the molecular mechanisms that affect the brains of mice on drugs. Learn how different drugs create different responses in the brain and alter the natural state of a mouse.

Protein Purification

This animation produced by WGBH and Digizyme, Inc. demonstrates how a protein of interest is isolated from other contents in a transformed bacterial cell—a process called purification—using a lab technique called hydrophobic interaction chromatography.
