Virus Imaged in Great Detail
WEST LAFAYETTE, Ind., March 6, 2008 -- Single-particle electron cryomicroscopy, also known as cryo-EM, has been used to capture a 3-D image of a virus with near atomic-level resolution, the highest level of detail achieved for a living organism of that size.
A team led by Wen Jiang, an assistant professor of biological sciences at Purdue University, captured the virus images at a resolution of 4.5 Å (angstroms), a level of detail two times greater than had previously been achieved. (It takes about 1 million angstroms to equal...
