Abstract
Durch thermische Denaturierung geht die ImmunogenitÄt von Sojaprotein verloren. Inkubation mit 6m-Guanidin-HCl stellt die ImmunogenitÄt wieder her. Durch dieses Reagens wird die bei Autoklavieren beobachtete Assoziation eines Teils der Sojaproteine wieder rückgÄngig gemacht. Dies dürfte die Hauptursache für die Rückgewinnung der ImmunogenitÄt sein. Diese Befunde werden im Zusammenhang mit der Bestimmung von autoklaviertem Sojaprotein durch zwei immunologische Verfahren diskutiert: Solid-Phase Radioimmunoassay und passive HÄmagglutination (Inhibitionsverfahren). Soy-bean protein loses its immunogenicity by heat treatment through thermal denaturation. Incubation with 6m guanidine-hydrochloride restores the immunogenicity. This reagent causes dissociation of protein aggregates formed during autoclaving of soy protein. This seems to be the major step in the restitution of immunogenicity. These findings are discussed in connection with the quantification of heat-denaturated soy-bean protein by two independent immunologic methods: Solid-Phase Radioimmunoassay and Passive Hemagglutination (inhibition test).This publication has 12 references indexed in Scilit:
