摘要： Disclosed is novel means for favorably maintaining the dispersed state of a latex reagent in an immunoassay kit and preventing occurrence of coagulation/sedimentation due to temperature changes so that the reagent is protected from deterioration in the measurement performance, which means is also applicable to an immunoagglutination assay kit containing a latex reagent aliquoted in small amounts. The immunoassay reagent of the present invention comprises unsensitized latex particles and trimethylglycine in a solvent. The concentration of trimethylglycine in the reagent is preferably 5 to 10 w/v %. The reagent can be favorably used as an immunoassay reagent for, e.g., hemoglobin A1c.
