Title
(EN) BUFFER COMPOSITION FOR REAGENTS FOR IMMUNOASSAY
(FR) COMPOSITION TAMPON POUR REACTIFS DE DOSAGE IMMUNOLOGIQUE
Abstract
(EN)
An aqueous composition suitable for use when performing immunological procedures. The composition includes at least one biological buffer, dithiothreitol (alternatively referred to herein as 'DTT'), and ethylene glycol. The composition can also include at least one biological detergent, at least one source of positive and negative counterions, e.g., salt, and at least one viscosity modifier, e.g., sugar. The buffer also can include at least one preservative, such as sodium azide. The pH of the composition preferably ranges from about 6.4 to 7.2. A kit containing the composition is also disclosed.
(FR)
Composition aqueuse pouvant être utilisée dans des techniques immunologiques. Elle comporte au moins un tampon biologique, le dithiothréitol (autrement dénommé ici 'DTT') et de l'éthylèneglycol. Elle peut également inclure au moins un détergent biologique, au moins une source de contre-ions positifs et négatifs, par exemple du sel, et au moins un modificateur de viscosité, par exemple du sucre. Le tampon peut également comporter au moins un agent conservateur, tel qu'azide de sodium. Le pH de la composition est de préférence compris entre 6,4 et 7,2 environ. L'invention décrit aussi un nécessaire contenant ladite composition.
