The role of the nonionic surfactant Tween 80 on the behavior of the therapeutic recombinant protein Factor VIII (rFVIII) was investigated at solid/liquid and air/water interfaces. In order to provide a model system to compare results obtained for the complicated rFVIII-Tween system, a well-characterized globular protein lysozyme was used. The...
Adipic dihydrazide-modified heparin was prepared and
subsequently immobilized on surface-activated silica wafers. X-ray
photoelectron spectroscopy (XPS) was used to quantify the elemental
composition of the silica surface at each stage of activation and results
showed that successful immobilization had taken place. Contact angle
measurements were made to verify the high...
