Problems solved by technology

However, because the source of urine protein is very complex, and is affected by factors such as environmental diet, physiological fluctuations are very large, which has led to the fact that these disease-related protein markers have not been widely used clinically due to specificity and stability issues.

Embodiment 1

[0141] This example illustrates that urine is selected as the research object for finding stable urinary protein markers in healthy people, and the stable protein markers in the urine of healthy people are used as indicators for early screening of urinary system diseases.

[0142] 1. Experimental method

[0143] 1. Screening of healthy donors

[0144] 100 healthy men and 100 healthy women were selected from the students of Chongqing Third Military Medical University. For specific physical examination indicators, see Table 1.

[0145] Table I

[0146]

[0147] 2. Specimen collection

[0148] Urine samples were collected every two months for a total of 3 collections. Collect 50ml of mid-morning urine each time at 8:00am, centrifuge at 3000rpm / min for 20 minutes at 4°C, keep the supernatant, and store at 4°C.

[0149] 3. Treatment of urine

[0150] Immediately after urine collection, one protease inhibitor cocktail tablet (Complete™; Roche Diagnostics, Mannheim, Germany) ...

Embodiment 2

[0185] This embodiment provides multiple embodiments of the kit of the present invention, and those skilled in the art can modify these embodiments according to the embodiments exemplified below in conjunction with the teachings of the present invention, and the scope of the present invention also includes these modifications implementation plan.

[0186] For the convenience of description, in Table 6 below, if not specified, monoclonal antibody is used as an example for the capture reagent of antibody-antigen binding mode; high-affinity receptor or ligand is used as an example for receptor-ligand binding mode. At the same time, in order to simplify the description, the kits listed in Table 6 only list the main components, such as capture reagents, detection reagents, detectable marker molecules, etc., while other optional components such as diluents, buffers, cleaning agents, etc. are omitted. At the same time, only the detection methods of detectable marker molecules are giv...

Abstract

The invention relates to a testing kit and a testing method for early screening or assisting diagnosis of urinary system diseases. The testing kit contains at least one testing reagent and a capturing reagent and can be used for specifically recognizing and correctly quantifying any one or combination of more proteins of COL6A1, GC, RBP4, DNASE1, GAA, SERPING1, CTSD, KNG1, UMOD, PIGR, AHSG, A1BG, AMBP, AZGP1, PTGDS, HPX, CD14 and ORM1 which are stably expressed in the urine of healthy people. The testing method can test whether the content of any of the eighteen proteins in the urine of a person to be tested is abnormal so as to prompt the generation of the urinary system diseases and achieve the purpose of early screening or assisting the diagnosis of the urinary system diseases.

Description

technical field [0001] The invention relates to a detection kit and a detection method for early screening or auxiliary diagnosis of urinary system diseases or pathological conditions. Specifically, the present invention relates to the screening of 18 marker candidate proteins stably expressed in the urine of healthy people, their use, a detection kit containing them as urinary system disease markers, and a detection method thereof. Background technique [0002] It is of great significance to detect or assist in the diagnosis of urinary system diseases through early screening, especially malignant diseases of the urinary system such as tumors, etc., for the prevention and cure of diseases. The source of urine is simple, convenient and non-invasive, and is easily accepted by patients without discomfort or contraindications. Urine can reflect the overall condition of the kidney, and can more timely and accurately reflect the physiological state and functional level of the kid...
