It's a tremendously complex undertaking, of course, and there are many ways for it to go wrong. The new technical guidelines, from a team led by Wladek Minor, Ph.D., of the University of Virginia School of Medicine, aim to prevent that.

"The compilation of the best practices and potential pitfalls for the accurate characterization of a metal binding site in any protein or virus is no easy task, and requires years of combined experience and efforts from many researchers from different areas of expertise," Minor said. "We hope that our research will improve the quality and reliability of research that involves handling metal-containing samples and eventually contribute to promoting research reproducibility in both academic and commercial settings."
