Here is a PDF file for setting a Protein crystal slide. Hope this may help you to set lysozyme protein crystal slide.

As a part of Life science research field, dealing with a protein is common practice. And multiple forms of proteins in our body act as transporters, receptors, enzymes, signal transducers etc. But how does a protein work? The answer to this question can be given by resolving the structure of that protein. As the biological activity of a protein lies in its structure. So crystallization is one of the ways to resolve it.
Solving a protein structure opens doors for many studies like designing drugs against the active site of the protein, blocking receptors using small molecule, you can solve the metabolic pathways etc.
