Immunological reagent consisting of special latex particles based on a vinylpolymer covered with an immunologically active material; process for its preparation; use of this reagent; analysing process using this reagent and test-kit containing this reagent

摘要

A reagent for an immunological determination comprising water insoluble latex particles being formed from vinyl polymerizates and having free terminal functional groups of the formula: IMAGE through which are bound an immunologically active material including materials for preparing this reagent and for utilizing this reagent for diagnostic purposes. The latex particles contain a core and an outer layer, said core being formed by polymerization of vinyl, or diene monomers or mixtures thereof with said polymerizates in said core carrying a functional group selected from group consisting of carboxyl, sulfonate or mixtures thereof and said outer layer being formed from vinyl polymerizates carrying said terminal functional group.
