Signature: Molecular voyeur

Among the methods used to describe the structures of complex molecules such as proteins, none is capable of assessing the structure or changes in structure of molecules interacting in a natural environment such as water or saline. Techniques like x-ray crystallography provide only a frozen snapshot of a protein, revealing limited information about the protein's function. Signature BioScience Inc. believes it has found a way to watch molecules as they interact in physiological environments by capitalizing on an existing
