Example Embodiment
[0031] The present invention will be described in detail below in conjunction with preferred embodiments.
[0032] In the following examples, the kits all include a luminescent substrate, a magnetic particle coupled antibody, and an enzyme-labeled antibody (horseradish peroxidase-labeled NT-proBNP monoclonal antibody).
[0033] The percentages in the present invention are volume fractions unless otherwise specified.
[0034] Examples of preparation and detection methods of the kit of the present invention:
[0035] 1. Preparation of the kit
[0036] 1. Preparation of magnetic particle conjugated antibody
[0037] The magnetic particle coupled antibody is used as a fixed separation phase. The antibody in the magnetic particle coupled antibody is the NT-proBNP monoclonal antibody. The concentration of the magnetic particle used for coupling is 1-10 mg / mL. The concentration is 1-5μg / mL, the size of the magnetic particles is 0.1μm-5μm, and the active groups on the surface of the magnetic ...
