Structural information from multilamellar liposomes at full hydration: Full q-range fitting with high quality x-ray data

G Pabst, M Rappolt, H Amenitsch, P Laggner - Physical Review E, 2000 - APS
We present a method for analyzing small angle x-ray scattering data on multilamellar
phospholipid bilayer systems at full hydration. The method utilizes a modified Caillé theory …

Long-term stability of sterically stabilized liposomes by freezing and freeze-drying: Effects of cryoprotectants on structure

B Stark, G Pabst, R Prassl - European journal of pharmaceutical sciences, 2010 - Elsevier
Liposomes are widely investigated for their use as drug delivery systems, where they have
to meet strict stability criteria. Hence, it is of common interest to establish appropriate storage …

[HTML][HTML] Rigidification of neutral lipid bilayers in the presence of salts

G Pabst, A Hodzic, J Štrancar, S Danner, M Rappolt… - Biophysical journal, 2007 - cell.com
