Zusammenfassung:The invention consists in a process for determining the presence of a specific IgE in human sera, characterised in that it comprises the following steps: binding of previously purified complex protein extracts upon a solid support, followed by incubation of the serum sample with the said bound protein extracts: washing non-specific proteins; incubation with anti-IgE monoclonal antibody labelled with I or with an enzyme; subsequent washing of the solid support with the bound products and determination of the radioactivity or enzymatic activity incorporated into the solid support. L'INVENTION CONSISTE EN UN PROCEDE POUR DETERMINER LA PRESENCE DE IGE SPECIFIQUE DANS DES SERUMS HUMAINS, CARACTERISE EN CE QU'IL COMPREND LES ETAPES SUIVANTES: FIXATION D'EXTRAITS PROTEIQUES COMPLEXES, PURIFIES AU PREALABLE, A UN SUPPORT SOLIDE, SUIVIE DE L'INCUBATION DE L'ECHANTILLON DE SERUM AVEC LESDITS EXTRAITS PROTEIQUES FIXES: LAVAGE DES PROTEINES NON SPECIFIQUES; INCUBATION AVEC L'ANTICORPS MONOCLONAL ANTI-IGE MARQUE AVEC I OU AVEC UNE ENZYME; LAVAGE POSTERIEUR DU SUPPORT SOLIDE AVEC LES PRODUITS FIXES, ET DETERMINATION DE LA RADIOACTIVITE OU DE L'ACTIVITE ENZYMATIQUE, INCORPOREE AU SUPPORT SOLIDE.
