WebTwo of the most commonly used methods for protein crystallization fall under the category of vapor diffusion. These are known as the hanging drop and sitting drop methods. Both entail a droplet containing purified … WebWith increasing distance from the protein, the water peaks decrease in height, and beyond approximately 6A they merge into the structureless solvent continuum, typical of most crystalline proteins. A few water sites are often found within the protein molecule. These water molecules appear to be trapped within the protein and presumably are more ...
