Comparative study on pseudoanaphylactoid reactions induced by medicinal tween 80 and injectable tween 80

China Journal of Chinese Materia Medica, 2012
OBJECTIVE To investigate the safety of different level of tween 80 by comparing the degree of pseudoanaphylactoid reactions (PR) induced by medicinal tween 80 and injectable tween 80. METHOD The analysis of vascular permeability of the mice ears: ICR mouse were divided into different test groups, the mice were intravenously injected with solutions of ...

Kinetic spectrophotometric determination of Tween 80

Talanta, 2004
A 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.

Enhancement of fibrinolysis and thrombolysis by polysorbate 80 (Tween 80®)

Experientia, 1967
Polysorbate 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.

The versatility of polysorbate 80 (tween 80) as an ionophore

Journal of Pharmaceutical Sciences, 1999
A number of experiments were performed to illustrate the unusual versatility of Polysorbate 80 (Tween 80) as an ionophore. New ions shown to be transported by it from and to water layers through a model membrane (CH2Cl2) include H3O+, Li+, Pb2+, Co2+, piperidinium ion, guanidinium ion, and Paraquat, while two complex ions resisted transport under the ...

Effect of Tween 80 on lipid vesicle permeability

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1983
As 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 ...

Enhancement of bile tolerance in lactococci by Tween 80

Journal of Applied Microbiology, 2002
The aim of this study is to clarify the effect of Tween 80 on bile tolerance of lactococci.Four out of the six strains of lactococci could grow in broth containing 0.3% bile in the presence of 1% Tween 80, but grew slightly or not at all in the absence of Tween 80.

Immunosuppressive Effects of Tween 80 on Mice

International Archives of Allergy and Applied Immunology, 2009
The 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.

Effects of the detergent Tween 80 on Thermomonospora curvata

World Journal of Microbiology and Biotechnology, 1994
Tween 80 (0.1%, v/v) added to Thermomonospora curvata growing in minimal medium caused a transient lowering of the dry cell mass, decreased the optimal growth temperature of the thermophile from 62 to 54°C, and increased extracellular esterase activity.

Interference of the detergent Tween 80 in protein assays

Analytical Biochemistry, 1992
The nonionic detergent Tween 80, which has been widely used to stimulate protein secretion in bacterial and fungal systems, caused interferences in three protein determination methods. The OD595 developed in the Coomassie blue dye-binding assay with a variety of purified proteins in the presence of Tween 80 was 1.6 to 3.4 times greater than that ...
