Kurzfassung englisch:
A rugged setup for mid-IR transmission measurements at large optical paths using an EC-QCL was employed for monitoring beta-aggregation in alcohol-denaturated proteins. Exposure of beta-rich alpha-chymotrypsin to 2,2,2-trifluoroethanol leads to immediate formation of nonnative alpha-helices. The subsequent gradual transition to intermolecular beta-sheet aggregates was monitored by mid-IR laser transmission spectroscopy. Multivariate curve resolution (MCR) was employed for analysis of spectral and concentration profiles of the temporal transition between alpha-helices an intermolecular beta-sheets
