Crystallization of a soluble protein.
Lysozyme forms tetragonal crystals.
An example of a lysozyme crystal grown in this class in previous year is shown below at left sitting on the stir-bar. The concentric rings are due to ice on the crystal. Due Sept. 20. The detailed techniques involved in collecting and analyzing X-ray diffraction patterns are beyond the scope of what can be experienced in this course. However, one of the main obstacles to solving a protein s structure remains the growth of adequate crystals, and we can fairly easily get some real laboratory experience with approaches commonly used to accomplish this.
