Embodiment 1

[0033] Example 1: Preparation of 11-dehydro-thromboxane B2 assay kit

[0034] 1. Preparation of reagent R1:

[0035] 0.015 mg of the 11dhTxB2 monoclonal antibody was weighed and dissolved in 100 ml of 10 mmol / L Tris buffer to make it completely dissolved, and filtered through a 0.22 μm membrane to prepare 0.015% (W / V) reagent R1.

[0036] 2. Preparation of reagent R2:

[0037] Using 30nm hydroxylated polystyrene nano latex particles, add EADC:Sulfo-NHS:Nanolatex particles to MES buffer with pH=6.0, the mass ratio is 1:0.5:0.1, ultrasonic for 2-3 seconds, and mix well , activated on a rotary shaker for 2 hours at room temperature, centrifuged at 17,000 rpm for 30 minutes, washed 3 times with MES buffer with pH=6.0, and then suspended the microspheres in HEPES buffer with pH=8.0 to make a microparticle suspension, and measure the particles. diameter and CV value.

[0038] To the 30nm particle suspension, add 11dhTxB2 protein with a mass of 1 / 3 the weight of the nanolatex part...

Embodiment 2

[0043] Example 2: Preparation of 11-dehydro-thromboxane B2 assay kit

[0044] The difference from Example 1 is that 2% (W / V) reagent R1 and 2% (W / V) reagent R2 were prepared, wherein 400 nm hydroxylated acrylate nanolatex particles were used in the preparation of reagent R2.

Embodiment 3

[0045] Example 3: Preparation of 11-dehydro-thromboxane B2 assay kit

[0046] The difference from Example 1 is that 1% (W / V) reagent R1 and 1% (W / V) reagent R2 are prepared, wherein 200 nm hydroxylated divinylbenzene nanolatex particles are used in the preparation of reagent R2 .

Abstract

The invention discloses a 11-dehydro-thromboxane B2 determination kit. The kit comprises: a reagent R1 including 0.01-2% (w / v) of 11dhTxB2 antibody and a buffering solution; a reagent R2 including 0.1-2% (w / v) of a 11dhTxB2 protein coated latex nanoparticle buffering solution; a calibrating substance comprising the 11dhTxB2 protein and a buffering solution; and a quality control substance which is a 11dhTxB2 protein dissolved in artificial urine. The 11-dehydro-thromboxane B2 determination kit improves the sensitivity and the linear range of detection of the 11-dehydro-thromboxane B2 content of urine, the detection sensitivity can reach 775pg / ml, and the linear range can reach 0-6300pg / ml. The 11-dehydro-thromboxane B2 determination kit has the advantages of high sensitivity, good specificity, high accuracy, good precision and good stability.

Description

technical field [0001] The invention relates to a detection kit, in particular to a 11-dehydro-thromboxane B2 detection kit, and also relates to the application of the kit. Background technique [0002] Due to the antiplatelet effect of aspirin, high-risk patients can reduce the incidence of arterial thrombotic events by about 25%. However, in patients with arterial thrombosis who received aspirin therapy, 10% to 25% of patients with arterial thrombosis will relapse during long-term follow-up. This phenomenon is called aspirin resistance or drug resistance. The emergence of this point of view has made people question the effectiveness of aspirin, because after taking aspirin, the platelet function of quite a few patients is still normal. [0003] Hungarian scholar Pusch et al. conducted a systematic review of the relevant data on the incidence of aspirin resistance and its clinical relationship before 2008. They found that although there is currently no widely accepted sta...
