Here are a few images of Lysozyme crystals
grown by students in the Chemistry 100 Lab

The crystals were grown with the gel-acupuncture technique. The gel used is Jell-O. The gel holder is a clear, plastic 35mm FUJI film canister (our thanks to FUJI for supplying us with the canisters). The precipitant is salt water and the protein is lysozyme from egg-whites.

A Nikon SMZ-10A stereomicroscope (supplied by Research Corporation) with a Pixera digital camera and Macintosh G3 computer were used to view and take pictures of the crystals.
