Crystallography protein
WebMar 11, 2024 · “Protein Crystallography is a form of very high-resolution microscopy, which enables scientists to “see” at atomic resolution. It allows us to see beyond the capabilities of even the most powerful light … WebWhile it is an immensely powerful tool for analyzing protein structure, crystallography has two major drawbacks. First, it relies on a researcher being able to get a protein to form regular, ordered crystals, which can be very challenging. Most proteins are globular, meaning they are (very roughly) spherical in shape.
