Interaction of Lung Surfactant Proteins with Anionic Phospholipids

Interaction Of Brain And Erythrocyte Spectrin With Anionic Phospholipids.

Spectrin, previously identified as one of the major proteins of the mammalian erythrocyte skeleton, was discovered in most animal cells. Brain spectrin, also known as fodrin, is one of the best studied nonerythroid proteins of the spectrin family. Erytrocyte spectrin can interact with the lipid domains in natural membranes and in model systems. We have found, that brain spectrin interacts with ...

Nanoparticle interaction with model lung surfactant monolayers.

One of the most important functions of the lung surfactant monolayer is to form the first line of defence against inhaled aerosols such as nanoparticles (NPs), which remains largely unexplored. We report here, for the first time, the interaction of polyorganosiloxane NPs (AmorSil20: 22 nm in diameter) with lipid monolayers characteristic of alveolar surfactant. To enable a better understanding,...

Interaction of Anionic Azo Dye and TTAB - Cationic Surfactant

A interação entre três corantes aniônicos azo: C.I. Vermelho Ácido 14 (AR14), C.I. Vermelho Ácido 1 (AR1), C.I. Laranja Ácido 7 (AO7) e um surfactante catiônico, o brometo de tetradeciltrimetilamônio (TTAB), foi investigada por meio da técnica de eletrodo seletivo para surfactante. O eletrodo seletivo para TTAB foi construído e usado para determinar a concentração de monômeros TTAB e, também, d...

Affinity precipitation of proteins by surfactant-solubilized, ligand-modified phospholipids.

The use of ligand-modified phospholipids solubilized in aqueous solution by nonionic surfactant for affinity precipitation of proteins is described. Avidin was precipitated by contact with solutions in which dimyristoylphosphatidylethanolamine (DMPE) functionalized with biotin (DMPE-B) was solubilized in octaethylene glycol mono-n-dodecyl ether (C12E8) solutions. The nonionic surfactant solubil...
