Langmuir−Blodgett Films of Fluorinated Glycolipids and Polymerizable Lipids and Their Phase Separating Behavior
2010
This paper describes the phase separating behavior of Langmuir monolayers from mixtures of different lipids that (i) either carry already a glycopeptide recognition site or can be easily modified to carry one and (ii) polymerizable lipids. To ensure demixing during compression, we used fluorinated lipids for the biological headgroups and hydrocarbon based lipids as polymerizable lipids. As a representative for a lipid monomer, which can be polymerized in the hydrophilic headgroup, a methacrylic monomer was used. As a monomer, which can be polymerized in the hydrophobic tail, a lipid with a diacetylene unit was used (pentacosadiynoic acid, PDA). The fluorinated lipids were on the one hand a …
Synthesis and Antibody Binding of Highly Fluorinated Amphiphilic MUC1 Glycopeptide Antigens
2011
The analysis of humoral immune responses is of great importance for basic and clinical research. Mapping the structural requirements of epitope recognition with modified tumor-associated carbohydrate antigens allows both the development of biomarkers and the design of synthetic anticancer vaccines. For this purpose, double-tailed hydrocarbon/fluorocarbon membrane anchors have been prepared and conjugated to a TN dipeptide. Furthermore, a novel hydrophobized MUC1 tandem repeat glycopeptide antigen was fully assembled on a solid support and its specific binding to different mouse anti-MUC1 antibodies was demonstrated through ELISA, QCM, and SPR measurements. Such functional fluorous MUC1 anti…
