Abstract

L'invention concerne des tampons utilisés pour stabiliser les isoenzymes à l'aide de formulations qui, après séchage et reconstitution, recouvrent la quasi-totalité de l'activité isoenzymatique et de la masse immunologique pour une longue durée de conservation, sans dissociation ni réarrangement de leurs sous-unités. Le tampon utilisé pendant le long stockage à sec de l'isoenzyme est un tampon aqueux exempt de sérum et de sels, comprenant 1) un sucre vitrifiant, 2) un mélange antioxydant, 3) un tampon pH et 4) un tensioactif non ionique et/ou un polymère synthétique et/ou une gélatine. Le tampon utilisé pour la reconstitution d'un échantillon enzymatique sans sérum et sans sel comprend un tampon aqueux à teneur en sel. L'invention porte également sur un isoenzyme sérique comprenant 1) un tampon pH, 2) un sel, 3) un mélange antioxydant et 4) un tensioactif non ionique et/ou un polymère synthétique et/ou une gélatine. La figure montre la stabilisation accélérée de la masse enzymatique dans un tampon aqueux avec du sérum et dans un tampon aqueux sans sérum, déterminée à l'aide d'un graphique d'Arrhénius, représentant le nombre de jours nécessaires à une stabilisation, en relation inverse avec la température, pour extrapoler une conservation de longue durée à 5 ~C.
