"This is one of the first projects to refine the technique to the point of near atomic-level resolution," said Jiang, who also is a member of Purdue's structural biology group. "This breaks a threshold and allows us to now see a whole new level of detail in the structure. This is the highest resolution ever achieved for a living organism of this size."
Details of the structure of a virus provide valuable information for development of disease treatments, he said.
"If we understand the system - how the virus particles assemble and how they infect a host cell - it will greatly improve our ability to design a treatment," Jiang said. "Structural biologists perform the basic science and provide information to help those working on the clinical aspects."
New technique takes a big step in examination of small structures
