X-ray photon correlation spectroscopy of hydrated lysozyme at elevated pressures
Milla Åhlfeldt, Maddalena Bin, Anita Girelli +12
Pressure provides a powerful parameter to control the protein conformation state, which at sufficiently high values can lead to unfolding. Here, we investigate the effects of incre…
Nanoscale Protein Diffusion in Supercooled Cryoprotectant Solutions
Maddalena Bin, Anita Girelli, Mariia Filianina +15
Vitrification during cryopreservation requires a quantitative understanding of protein transport in deeply supercooled cryoprotectant solutions, yet direct measurements at molecula…
Depletion-Induced Interactions Modulate Nanoscale Protein Diffusion in Polymeric Crowder Solutions
Michelle Dargasz, Nimmi Das Anthuparambil, Sebastian Retzbach +26
Macromolecular crowding plays a crucial role in modulating protein dynamics in cellular and in vitro environments. Polymeric crowders such as dextran and Ficoll are known to induce…
Softness and Hydrodynamic Interactions Regulate Lipoprotein Transport in Crowded Yolk Environments
Nimmi Das Anthuparambil, Michelle Dargasz, Sonja Timmermann +27
Low-density lipoproteins (LDLs) serve as nutrient reservoirs in egg yolk for embryonic development and as promising drug carriers. Both roles critically depend on their mobility in…
3D evolution of protein networks and lipid globules in heat-treated egg yolk
Felix Wittwer, Nimmi Das Anthuparambil, Frederik Unger +5
Upon heating, egg yolk transforms from a liquid to a gel due to protein denaturation. This process can serve as a useful model to better understand protein denaturation in general.…
Coherent X-rays reveal anomalous molecular diffusion and cage effects in crowded protein solutions
Anita Girelli, Maddalena Bin, Mariia Filianina +38
Understanding protein motion within the cell is crucial for predicting reaction rates and macromolecular transport in the cytoplasm. A key question is how crowded environments affe…
On the analysis of two-time correlation functions: equilibrium vs non-equilibrium systems
Anastasia Ragulskaya, Vladimir Starostin, Fajun Zhang +2
X-ray photon correlation spectroscopy (XPCS) is a powerful tool for the investigation of dynamics covering a broad range of time and length scales. The two-time correlation functio…
Nanoscale Rigidity in Cross-Linked Micelle Networks Revealed by XPCS Nanorheology
M. Reiser, J. Hallmann, J. Möller +11
Solutions of wormlike micelles can form cross-linked networks on microscopic length scales. The unique mechanical properties of these complex fluids are driven by the interplay bet…
