Research at Argonne's Advanced Photon Source reveals structure and behavior of collagen

... discovered that it had a triple-stranded helical structure. However, researches had never before had the ability to study the structure of an entire fibril in the same way that they could study an individual collagen molecule, according to Orgel.

...evolution of fibrils, They can thus develop a better understanding of amyloid aggregation. The scientists are also seeking the precise point during fibril formation when interactions between monomers become irreversible. Defining that point is important because "the fibrils are virtually indestructible o...

First ASMS Hites Award for Outstanding Research Publication Presented to Prof. Alison Ashcroft for Her Use of Waters Synapt HDMS System to Explore Protein Complexes

...-Jakob's, and Parkinson's, can develop when certain proteins become misfolded, causing a chain of events that can lead to self-aggregation and amyloid fibril formation. Thus determining a protein's folded state is important and mass spectrometry is unique in its ability to monitor independently co-populated...
