Embodiment 1

[0026] A kit for the determination of triiodothyronine, comprising goat monoclonal antibody-coated magnetic beads, ANS dissociation agent and enzyme working solution, and the goat monoclonal antibody-coated magnetic beads are marked with biotin.

[0027] The preparation method of the goat monoclonal antibody-coated magnetic beads is:

[0028] A. Take 0.25 mg of goat monoclonal antibody and use 5L of 0.2mmol / L PBS (PH7.4) buffer for dialysis at 2~8℃ overnight.

[0029] B. Take out the dialyzed goat monoclonal antibody in an appropriate container, accurately measure the volume and record, and dilute the goat monoclonal antibody to 0.5 mg / mL for use.

[0030] C. Weigh 1.0 mg of BNHS, fully dissolve it with 217 μL of DMSO, and prepare a 10 mmol / L BNHS solution.

[0031] D. Add the prepared BNHS to goat monoclonal antibody at a ratio of 20:1 to the dialysis goat monoclonal antibody, mix well and react at room temperature for 30 minutes. That is, 1.0 mg of antibody was added to 13.3 μL of 10...

Abstract

The invention provides a kit used for determination of triiodothyronine. The invention aims to overcome the problems of poor specificity and poor sensitivity of conventional T3 immunoassay reagents. The kit used for determination of triiodothyronine comprises magnetic beads coated by a goat monoclonal antibody, an ANS dissociation agent and an enzyme operation fluid, wherein the magnetic beads coated by the goat monoclonal antibody is labeled with biotin. The kit provided by the invention employs the magnetic beads coated by the goat monoclonal antibody; magnetic particles (the magnetic beads) are coated by anti-biotin antibody which is the goat monoclonal antibody; so the kit has higher specificity and sensitivity compared with the conventional T3 immunoassay reagents.

Description

Technical field [0001] The invention relates to a kit, in particular to a kit for determining triiodothyronine. Background technique [0002] Triiodothyronine (T3) is a small molecule project. The antibodies of existing T3 immunoassay reagents are generally polyclonal antibodies or mouse monoclonal antibodies, which are lacking in specificity and sensitivity. The prior art does not dilute the antibody to be labeled to a fixed concentration, and it is inconvenient to operate when labeling a small amount of antibody. At the same time, the difference between batches is large, and the function difference of kits of different batches is large, resulting in low stability. Summary of the invention [0003] The invention provides a kit for determining triiodothyronine, which aims to solve the problem of poor specificity and sensitivity of T3 immunoassay reagents in the prior art. [0004] In order to solve the above technical problems, the present invention is achieved through the followin...
