Abstract
L'invention concerne des compositions et des procédés de détection de nombreux mélanges cibles à analyser dans un échantillon au moyen de microparticules présentant des marqueurs moléculaires qui sont fixés par des liaisons pouvant être coupées. De manière générale, un mélange d'analyse est formé et comprend un échantillon et un réactif comprenant de nombreuses microparticules dans un état permettant à des complexes stables de se former entre les fractions de liaisons sur lesdites surfaces des microparticules et lesdits mélanges à analyser. Selon un aspect de l'invention, une seconde composition de liaison est ajoutée de sorte que des complexes se forment parmi les fractions de liaison liées aux microparticules, lesdits mélanges à analyser, et les secondes fractions de liaison de la seconde composition de liaison. Lesdites secondes fractions présentent des fractions induisant le clivage fixées qui provoquent le clivage desdites liaisons et la libération des marqueurs moléculaires à la suite de l'activation. Lesdits marqueurs moléculaires libérés sont séparés et la présence et/ou la quantité des mélanges cibles à analyser sont déterminées sur la base de l'analyse des marqueurs moléculaires libérés et séparés.
