Catching Alzheimer's Toxin

Single-particle cryo-electron microscopy of  a functional Aβ42 pore equivalent, created by fusing Aβ42 to the oligomerizing, soluble domain of the α-hemolysin  toxin, offers new insights into structure and function of proteins forming amyloid aggregates in Alzheimer’s disease.

Application of synchrotron-XRPD to protein powders

Breakthrough applications of high-resolution and high-counting statistics synchrotron X-Ray Powder Diffraction to protein powders leading to the determination of a 1.8 structural model of the pharmaceutical peptide "octreotide" - the highest resolution ever achieved for a peptide of this complexity using X-ray powder diffraction and crystallographic methods.
