Abstract:
The present invention includes novel digoxin assays employing a capture reagent, involving a first binding member conjugated to a polymeric anion substance, and a solid phase material containing a reaction site comprising a polymeric cation substance having a nitrogen content of at least about two percent. A test sample suspected of containing the analyte of interest may be contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged solid phase to attract, attach, and immobilize the capture reagent/analyte complex.
Abstract:
Nouveaux procédés d'analyse de la digoxine faisant appel à un réactif de capture, mettant en jeu un premier membre de fixation associé à une substance anionique polymérique, et un matériau en phase solide contenant un lieu de réaction constitué d'une substance cationique polymérique d'une teneur en azote d'au moins environ 2 %. Un échantillon à analyser dans lequel on soupçonne la présence de l'analyte recherché peut être mis en contact avec le réactif de capture afin de former un complexe chargé contenant le réactif de capture et l'analyte. Le complexe est ensuite mis en contact avec la phase solide de charge opposée afin d'attirer, de fixer et d'immobiliser le complexe réactif de capture/analyte.
