Claims13
In a method of conducting an assay for an analyte in which one or more reagents soluble in the assay medium are dissolved in the assay medium and interact in the assay medium with another entity leading to an indication of the presence or absence of the analyte and wherein said reagent is in a form in which the dissolution of said reagent into the assay medium when contacted with the assay medium is delayed, the improvement which comprises said form being an association of said reagent with a delayed release agent comprising cross-linked polyvinyl alcohol wherein individual polymer chains are linked together by covalent bonds, whereby the precision of the assay is improved.
