Embodiment 1

[0171](1) Production of latex particles with an average particle diameter of 150nm

[0172] Suspend 30 g (288 mmol) of styrene (manufactured by FUJIFILM Wako Pure Chemical Corporation) and 3 g (42 mmol) of acrylic acid (manufactured by FUJIFILM Wako Pure Chemical Corporation) in 440 mL of ultrapure water, raise the temperature to 95° C., and add potassium persulfate (KPS) ( FUJIFILM Wako Pure Chemical Corporation (manufactured by FUJIFILM Wako Pure Chemical Corporation) 1 g was dissolved in an aqueous solution of 10 mL of ultrapure water, and stirred at 95° C. and 250 rpm for 6 hours. Thereafter, centrifugation was performed three times at 10,000 rpm for 6 hours to obtain latex particles. Finally, the obtained latex particles were dispersed in ultrapure water again. Pure water was added so that the solid content concentration became 1 mass %, and the diluted liquid was prepared. The average particle diameter of the latex particles was 150 nm when calculated as a median parti...

Embodiment 2

[0197] Prepare and use the fluorescent latex particles modified with the anti-SAA antibody used in Example 1, and further add the latex particles modified with the anti-CRP antibody that is not fluorescently labeled in a mass ratio of 5 times Except for drying the particles, in the same manner as in Example 1, the rate of increase in fluorescence signal value was determined for each of test samples No. 1 and No. 2.

Embodiment 3~9

[0199] In Example 1, instead of surfactant D316, the surfactants and concentrations shown in Table 1 were changed, and in the same manner as in Example 1, for test samples No.1 and No.2, respectively, the The increasing speed of the fluorescence signal value.

Abstract

The present invention addresses the problem of providing a reagent kit, measurement kit, and measurement method for immunologically measuring serum amyloid A with high accuracy and high sensitivity, without using an alcohol designated as a hazardous material in the fire protection code. The present invention provides a reagent kit that is for measuring serum amyloid A and that contains: first particles labelled and modified with a first binding substance capable of specifically binding to serum amyloid A; and at least one nonionic surfactant having a molecular weight of 1000 or less.

Description

technical field [0001] The invention relates to a test kit for measuring serum amyloid A, a test kit for measuring serum amyloid A and a method for measuring serum amyloid A in biological samples. Background technique [0002] Conventionally, in bioassays and the like, fluorescence detection methods have been widely used as highly sensitive and easy measurement methods. This fluorescence detection method is a method of confirming the presence of the detection target substance by detecting fluorescence at the time of irradiating a sample thought to contain a detection target substance excited by light of a specific wavelength to fluoresce with excitation light of the above-mentioned specific wavelength. In addition, when the detection target substance is not a fluorescent substance, a substance that specifically binds to the detection target substance labeled with a fluorescent dye is brought into contact with the sample, and then fluorescence is detected in the same manner a...
