TEST METHOD AND REAGENT KIT THEREFOR

Methods of assaying samples for the pres- ence of an analyte involving immobilisation of a gold sol, and optionally an enzyme capable of generating a characteristic reaction, on a solid phase. The gold sol has a mean particle size of less than 20 nanometres for at least 75% by weight of the particle...

Zusammenfassung:Methods of assaying samples for the pres- ence of an analyte involving immobilisation of a gold sol, and optionally an enzyme capable of generating a characteristic reaction, on a solid phase. The gold sol has a mean particle size of less than 20 nanometres for at least 75% by weight of the particles and is formed into a novel superaggregated complex with at least one pro- tein.
