DEGRADATION PREVENTING MEANS FOR IMMUNOASSAY REAGENT CONTAINING INSOLUBLE CARRIER PARTICLES

摘要

An object of the present invention is to find a component which can prevent non-specific flocculation of sensitized or unsensitized insoluble carrier particles contained in an immunoassay reagent when the reagent is frozen, to thereby provide means for preventing degradation of the immunoassay reagent. The component which can prevent non-specific flocculation of insoluble carrier particles is the following ω-aminocarboxylic acid (1) [wherein n is an integer of 2 to 6]. The invention provides an immunoassay reagent containing insoluble carrier particles and ω-aminocarboxylic acid (1), and a method for preventing degradation of an immunoassay reagent by using ω-aminocarboxylic acid (1).;
