Description

Technical Field

[0001] The present invention relates to the field of immunochromatographic detection, and particularly relates to an immunochromatographic detection kit for platelet GP IIb / IIIa receptor inhibition rate, a preparation method and a detection method. Background Art

[0002] Platelets play a key role in maintaining normal hemostasis. When exposed to damaged blood vessels, platelets will adhere to the exposed subendothelial matrix. Subsequently, various factors (such as thrombin, adenosine diphosphate (ADP) or collagen, etc.) released or generated at the injury site activate platelets. After platelet activation, the conformation of glycoprotein GPIIb / IIIa receptors on platelets changes, enabling them to bind to adhesion proteins such as fibrinogen, resulting in the recruitment of neighboring platelets to the injury site and aggregation to form a hemostatic plug or thrombus.

[0003] Currently, the commonly used antiplatelet drugs on the market are mainly cyclooxygenase-1 inhibitors (main representative drug: aspirin), P2Y12 receptor inhibitors (representative drugs: clopidogrel, prasugrel and ticagrelor), and GP IIb / IIIa inhibitors (representative drugs: abciximab, eptifibatide, tirofiban). GP IIb / IIIa receptor inhibitors block GP IIb / IIIa receptors in a reversible or irreversible manner, thereby preventing platelets from being activated through the GP IIb / IIIa receptor pathway.

[0004] Clinically, most patients taking GP IIb / IIIa receptor inhibitors have relatively serious and urgent thromboembolic risks. Therefore, for patients taking GP IIb / IIIa receptor inhibitors, monitoring their medication effects is of great significance. In actual situations, due to the differences in individual platelet function activities and drug efficacies, this may lead to patients taking GP IIb / IIIa receptor inhibitors not achieving the ideal medication effects. Therefore, clinically detecting the GP IIb / IIIa receptor inhibition rate of patients is very necessary for guiding their GP IIb / IIIa receptor inhibitor treatment.

[0005] Currently, there is no GP IIb / IIIa receptor inhibition rate detection product on the domestic market. Abroad, only VerifyNow has reported a GP IIb / IIIa detection product, but there is no report on an immunochromatographic method for detecting platelet GP IIb / IIIa receptor inhibition rate.

[0095] Optionally, it includes:

[0096] Quantitative detection method:

[0097] Take the test sample and add it to or not add it to the sample diluent, then drop it onto the sample pad of test strip A or the sample-binding integrated pad of test strip B. After 3 - 10 minutes, detect the fluorescence signals of the test line and the control line respectively, and calculate the platelet GP IIb / IIIa receptor inhibition rate through the following formula:

[0098] R = [1 - T / (T + C)] × 100%;

[0099] In the formula, R represents the platelet GP IIb / IIIa receptor inhibition rate;

[0102] Qualitative detection method:

[0103] Take the test sample and add it to or not add it to the sample diluent, then drop it onto the sample pad of test strip A or the sample-binding integrated pad of test strip B.

[0105] Optionally, the sample to be tested contains platelet-rich plasma or diluted platelet-rich plasma.

[0106] The technical solution of the present invention has the following advantages:

[0107] 1. An immunochromatographic detection kit for the inhibition rate of platelet GP IIb / IIIa receptor provided by the present invention includes: a test strip and a sample diluent; or a test strip; the test strip includes a bottom plate and a sample pad, a conjugate pad, a chromatographic membrane and a water absorption pad that are sequentially overlapped and lapped on the bottom plate, and the test strip is denoted as test strip A; or the test strip includes a bottom plate and a sample-conjugate integrated pad, a chromatographic membrane and a water absorption pad that are sequentially overlapped and lapped on the bottom plate, and the test strip is denoted as test strip B; in the test strip A and the sample diluent, or in the test strip A: the sample diluent, the sample pad and / or the conjugate pad contain a fluorescently labeled platelet surface-specific receptor antibody and an anti-red blood cell antibody; the sample pad, the conjugate pad and / or the chromatographic membrane are coated with thrombin receptor I activation peptide and thrombin receptor IV activation peptide; the chromatographic membrane is provided with a detection line and a quality control line at intervals, the detection line is coated with fibrinogen, and the quality control line is coated with a polyclonal antibody; in the test strip B and the sample diluent, or in the test strip B: the sample diluent and / or the sample-conjugate integrated pad contain a fluorescently labeled platelet surface-specific receptor antibody and an anti-red blood cell antibody; the sample-conjugate integrated pad and / or the chromatographic membrane are coated with thrombin receptor I activation peptide and thrombin receptor IV activation peptide; the chromatographic membrane is provided with a detection line and a quality control line at intervals, the detection line is coated with fibrinogen, and the quality control line is coated with a polyclonal antibody; in the above-mentioned kit, when detecting, after adding the sample, on the sample pad, the conjugate pad and / or the chromatographic membrane, while the thrombin receptor I activation peptide and the thrombin receptor IV activation peptide diffuse with the sample, the platelets in the sample to be tested are specifically activated by the thrombin receptor I activation peptide and the thrombin receptor IV activation peptide, and the activated platelets are captured by the fibrinogen coated on the detection line, and the unactivated platelets are captured by the polyclonal antibody coated on the quality control line. Since the sample diluent or the sample pad or the conjugate pad contains a fluorescently labeled platelet surface-specific receptor antibody, the fluorescently labeled platelet surface-specific receptor antibody can fluorescently label the activated and unactivated platelets in the sample to be tested. Therefore, by collecting the fluorescent signals on the detection line and the quality control line, the detection result can be signalized, and the inhibition degree of the GP IIb / IIIa receptor of the test sample can be qualitatively or quantitatively detected according to the fluorescent signals on the detection line and the quality control line. The same applies to test strip B.

[0108] Further, in quantitative detection, the fluorescence signals of the test line and the control line are collected, and the inhibition rate is calculated by the formula R = [1 - T / (T + C)] × 100%. The higher the inhibition rate, the higher the degree of inhibition of the GP IIb / IIIa receptor in the test sample, that is, the better the efficacy of the GP IIb / IIIa receptor inhibitor in the subject; on the contrary, the lower the inhibition rate, the worse the efficacy of the GP IIb / IIIa receptor inhibitor in the subject.

[0109] In summary, the kit of the present invention has high detection accuracy. It has been compared with the "gold standard" turbidimetry (LTA method). The comparison results show that the detection results of the present invention and the "gold standard" have good consistency.

[0110] 2. An immunochromatographic detection kit for the inhibition rate of platelet GP IIb / IIIa receptor provided by the present invention, wherein the platelet surface specific receptor antibody is a P2Y12 receptor antibody, a P-selectin receptor antibody, a prostaglandin receptor antibody, a platelet chemokine receptor antibody, and / or a 5-hydroxytryptamine receptor antibody; through long-term research, the present invention particularly selects the above-mentioned platelet surface specific receptor antibodies, and uses the platelet surface specific receptor antibodies labeled with fluorescent substances to achieve fluorescent labeling of platelets, so as to ensure that both activated platelets and unactivated platelets can be fluorescently labeled, and then the detection result signals can be obtained, and then qualitative and quantitative analysis of the detection results can be realized.

[0111] Further, anti-red blood cell antibodies are also coated on the sample pad and / or the conjugate pad. The anti-red blood cell antibodies can bind to the red blood cells in the whole blood sample to be tested, intercept the red blood cells, and avoid the red blood cells chromatographing onto the chromatographic membrane to generate background signals, which affect the detection of the signals of the test line and the quality control line, and further improve the detection accuracy. The same applies to test strip B. BRIEF DESCRIPTION OF THE DRAWINGS
