Abstract

L'invention concerne les dosages immunochimiques. Il s'agit d'un procédé de dosage de l'activité de LDH1 dans un échantillon de sérum, procédé qui comprend la combinaison des étapes suivantes : a. traitement dudit échantillon de sérum avec un premier anticorps immunologiquement sélectif de l'unité M des isoenzymes de LDH où lesdits complexes d'anticorps avec LDH2 , LDH3 , LDH4 et LDH5 sont présents dans ledit échantillon; b. traitement du produit de réaction immunologique de l'étape a avec un second anticorps immunogéniquement produit dans une espèce animale autre que l'espèce animale employée pour produire ledit premier anticorps ledit second anticorps étant insolubilisé sur un support en phase solide, par lequel on obtient un produit de réaction immunologigue entre le produit de l'étape a et ledit second anticorps insolubilisé; c. séparation dudit produit de réaction de l'étape b de la solution de surnageant; et d. dosage de l'activité de LDH1 de la solution de surnageant. Ce procédé permet de doser la LDH1 qui est un marqueur de l'infarctus du myocarde.
