Definitions

  • the present invention relates to diagnostic test devices for rapid detection of analytes using chemiluminescence in a strip format.
  • An advantageous shape is a thin layer lying over the opening although another shape such as a plug may be used, depending on the features of the strip. Fluid preferably moves traverse to the major surface of the reagent layer during transfer to the absorbent pad, although some device configurations may utilize lateral flow along the longest axis of a reagent layer.
  • the reagent layer is a nitrocellulose membrane with antibody bound to it. Preferred in this context is an antibody that reacts with lipopolysaccharide or H7 flagellar antigen from this bacterium.
  • the reagent layer need not be a "layer" per se, but may consist of a pad, rod or other shaped absorbent.

Abstract

Il est possible d'exécuter un essai sensible et rapide en combinant une détection par chimiluminescence avec un tampon à réactif à forte porosité et un tampon absorbant mobile afin d'agir sur le minutage de réaction. Le dispositif d'essai, la technique et les nécessaires correspondant conviennent à des épreuves d'immunodétection axés sur un anticorps ainsi qu'à des épreuves reposant sur des réactions d'hybridation de l'acide nucléique.
