Description

Technical Field

[0001] The present invention relates to the technical field of biomedical detection systems, and particularly to a production system and method for a high-sensitivity anti-JO-1 antibody CBA detection kit. Background Art

[0002] Autoimmune diseases, such as polymyositis and dermatomyositis, usually rely on the detection of specific autoantibodies in clinical diagnosis. Among them, anti-JO-1 antibody, as an important serological marker for polymyositis, has high clinical value. At present, conventional antibody detection methods have problems such as limited sensitivity, unstable specificity, and complex operation, making it difficult to meet the needs of accurate detection. With the development of cell genome analysis technology, magnetic microsphere technology, and microfluidic detection, new detection methods have gradually improved the sensitivity, stability, and automation of detection. However, in the industrial production process of the kit, technical challenges such as magnetic bead coupling efficiency, stability of freeze-dried microspheres, batch-to-batch consistency, and optimization of process parameters still exist. Therefore, there is an urgent need for an efficient, stable, and intelligent production system to improve the accuracy and batch stability of anti-JO-1 antibody detection and promote its wide application in the fields of clinical detection and disease monitoring.

[0003] Referring to the relevant publicly disclosed technical solutions, the solution with the publication number CN102621308A proposes a colloidal gold chromatography anti-Jo-1 antibody detection test strip and its preparation method. The colloidal gold chromatography anti-Jo-1 antibody detection test strip includes a sample pad, a conjugate pad, a nitrocellulose-coated membrane, and an absorbent pad. The sample pad, conjugate pad, nitrocellulose-coated membrane, and absorbent pad are sequentially pasted on the bottom plate from one side of the bottom plate to the other side of the bottom plate. The conjugate pad is coated with gold-labeled antibody a and gold-labeled antibody b; the nitrocellulose-coated membrane is provided with a test line and a quality control line. The test line is coated with Jo-1 antigen protein, and the quality control line is coated with gold-labeled antibody c. This solution adopts an indirect immunoassay method, introduces Jo-1 antigen protein, and optimizes the process of the conjugate pad and the sample pad to achieve high-sensitivity, high-specificity, and high-accuracy detection performance of anti-JO-1 antibody, providing a reference basis for the auxiliary diagnosis of dermatomyositis / polymyositis. However, this solution relies on the colloidal gold chromatography method, the detection sensitivity is limited, and the process optimization mainly focuses on the conjugate pad and the sample pad, without involving magnetic microsphere coupling, microfluidic technology, and intelligent quality monitoring, making it difficult to ensure batch stability and consistency of automated production.
