  • Method in assaying methods involving biospecific affinity reactions and reagent for use in said method
    Patent number: 4231999
    Abstract: A method of carrying out assaying methods involving biospecific affinity reactions in which there is used a component (I), which is labelled with at least one analytically indicatable group and is soluble in the liquid in whose presence the biospecific affinity reaction is carried out, for reaction with a counterpart (II) which exhibits biospecific affinity to (I) and optionally also one or more additional counterparts exhibiting biospecific affinity to (I) and/or (II), and forming an insoluble conjugate in which the labelled component (I) is incorporated and which conjugate is separated from the liquid phase, whereafter the analytically indicatable group is assayed in the insoluble conjugate, said method being characterized in that the analytically indicatable group is bound to the component (I) with a splittable bond of covalent nature and/or one of said counterparts is bound to a carrier, which is insoluble in said liquid, with a splittable bond of covalent nature, said splittable bonds being splittable un
