ABSTRACT:
Disclosed is a serum free control reagent formulation useful for the determination of a pre-selected analyte. The formulation involves an aqueous solution of a predetermined amount of the analyte together with a polymerized quaternary salt of di- or mono- allyl, di- or tri- alkyl ammonium characterized by the formulae: ##STR1## where R is straight or branched chain alkyl of 1 to 4 carbon atoms, n is a number of at least 9 and .theta. represents a counteranion. The formulation typically contains a buffer to maintain its pH at a level of about 7.5 and a preservative.
