Kinetic spectrophotometric determination of Tween 80
Talanta, 2004A novel kinetic spectrophotometic method for the determination of Tween 80 based on its interaction with 5(p-dimethylaminobenzylidene)rhodanine (PDR) in alkaline media is reported. The effect of variable on the rate of interaction of Tween 80 and PDR was investigated in order to establish the optimum conditions.

Comparative Analysis of the Properties of Tween‐20, Tween‐60, Tween‐80, Arlacel‐60, and Arlacel‐80
Journal of Dispersion Science and Technology, 2007Foamability and foam stability, emulsifying power, surface tension, and interfacial tension were investigated for Tween‐20 (polyoxyethylene sorbitan monolaurate), Tween‐60 (polyoxyethylene sorbitan monostearate), Tween‐80 (polyoxyethylene sorbitan monooleate), Arlacel‐60 (Sorbitan stearate), and Arlacel‐80 (Sorbitan oleate).

Enhancement of fibrinolysis and thrombolysis by polysorbate 80 (Tween 80®)
Experientia, 1967Polysorbate 80 (Tween 80®), eine polyhydroxyle, nicht-ionisierbare, oberflachenaktive Substanz, vermindert die Adsorption von Urokinase an Glas, erhoht deren fibrinolytische Aktivitat in vitro und steigert ihre thrombolytische Wirkung in experimentell hervorgerufenen Thrombosen im Kaninchen.

Dual effects of Tween 80 on protein stability
International Journal of Pharmaceutics, 2008In this paper, we used IL-2 mutein as a model protein and evaluated the effect of Tween 80, a non-ionic surfactant. In summary, we found that the dual effects of Tween 80 on the stability of IL-2SA, such as that shaking-induced aggregation of IL-2 mutein was significantly inhibited in the presence of Tween 80.

Effect of Tween 80 on lipid vesicle permeability
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1983As part of an examination of procedures for protein/lipid reconstitution we incubated solubilized cytochrome oxidase at different temperatures with preformed vesicles composed of saturated lipids. We observed that the 22Na permeability of these vesicles was increased following such an incubation step, with the maximal effect occurring following ...

Tween 80 enhanced TNT mineralization byPhanerochaete chrysosporium
Canadian Journal of Microbiology, 2000The effect of a nonionic surfactant (Tween 80) on 2,4,6-trinitrotoluene (TNT) mineralization by the white-rot fungus Phanerochaete chrysosporium strain BKM-F-1767, was investigated in a liquid culture at 20, 50, and 100 mg TNT·L-1. The presence of 1% (w/v) Tween 80, at 20 mg·L-1TNT, added to a 4-d-old culture, allowed the highest TNT mineralization ...

Immunosuppressive Effects of Tween 80 on Mice
International Archives of Allergy and Immunology, 1981The effects of Tween 80 on the humoral immune response, as measured by the Jerne plaque assay, was determined. Mice treated with Tween 80 showed a significant depression in the number of primary (IgM) plaques without a significant difference in the number of secondary (IgG) plaques.

Behavioral effects of vehicles: DMSO, ethanol, Tween-20, Tween-80, and emulphor-620
Pharmacology Biochemistry and Behavior, 1995Experimental drugs and compounds that do not easily dissolve in water or saline are frequently combined with vehicles like solvents, detergents, or vegetable oils. Yet very little has been reported on the behavioral effects of vehicles. In this study, we assessed the effects of a vegetable oil (emulphor-620), two detergents (Tween-20 and Tween-80), and
