ABSTRACT

Figure 5-5 Organic solvent extracts of lung tissue. Lung tissue homogenates contain nonsurfactant constituents as well as alveolar and intracellular surfactant. Lipids and other hydrophobic components from cells and tissue coextract in hydrophobic organic solvents along with surfactant lipids and hydrophobic proteins. Further physical or chemical processing of lung tissue extracts can be applied to enrich the final product in lung surfactant components. See text for details.
