摘要

A quantitative comparison of the penetration of dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC) and palmitoyloleoyl-sn-glycero-3-phosphatidylcholine (POPC) monolayers by various types of surfactants and polymers is presented. Surface pressure (Π)-area compression isotherms and Brewster angle microscopy (BAM) were used to investigate the incorporation of amphiphiles from a subphase solution into lipid monolayers. Parallel experiments were performed to study the effects of these same additives on cell growth in Chinese hamster ovary (CHO) cell cultures. Results show a strong correlation between additive effects on model lipid monolayers and their impact on cell growth and viability.
