Better metrics extend SAS capabilities
26 Apr 2013
Researchers from Berkeley Laboratory have improved the metrics for X-ray and neutron analysis of flexible macromolecules.
A team at Berkeley Laboratory has developed a new set of metrics for analysing data acquired via small angle scattering (SAS) experiments with X-rays (SAXS) or neutrons (SANS).
Among other advantages, they believe it will significantly cut the time required to collect data.
“SAS is the only technique that provides a complete snapshot of the thermodynamic state of macromolecules in a single image,” explained Robert Rambo, a scientist with Berkeley Lab’s Physical Biosciences Division.
In SAS imaging, beams of X-rays or neutrons sent through a sample produce tiny collisions between the X-rays or neutrons and nano or sub-nano sized particles within the sample.
