Problems solved by technology

[0006] This kit is mainly used for dynamic monitoring of patients with related malignant tumors to assist in judging the disease process or treatment effect. It cannot be used as the basis for early diagnosis or diagnosis of related malignant tumors, and it is not suitable for tumor screening in the general population.

Abstract

The invention relates to a plate-type chemiluminescence detection kit of a cytokeratin 19-fragment. The kit comprises the following reagents: biotin-marked CYFRA21-1 antibody solution, an elisa plate coated by anti-biotin, horse-radish-peroxidase-marked CYFRA21-1 antibody solution, a CYFRA21-1 calibration product A-F, concentrated washing liquor, substrate solution A, and substrate solution B. The main design idea of the detection kit is that the detection specificity of the kit is stabilized by introducing a biotin system with the anti-biotin on the basis of chemiluminescence immune assay, and the detection sensitivity and detection time are greatly increased. A high-temperature oscillatory-type anti-biotin coating technology is improved, so the usage amount of antibodies / antigens is reduced, the production flow of the reagents is simplified, and the production cycle is shortened.

Description

technical field [0001] The invention belongs to the field of biological kit materials, in particular to a quantitative detection kit for cytokeratin 19 fragments and a preparation method, which can quickly, easily, efficiently and sensitively quantify cytokeratin 19 fragments in human serum samples detection. Background technique [0002] Cytokeratin 19 fragment (Cytokeratin-19-fragment CYFRA21-1) is that when alveolar epithelial cells undergo apoptosis, the keratin fragments contained in the cells degrade and become soluble substances and enter the blood, increasing the blood content. [0003] CYFRA21-1 is the preferred marker for non-small cell lung cancer, especially for squamous cell carcinoma, with a sensitivity of 60% and a specificity of 95%. It is of great significance to the early diagnosis, curative effect monitoring and prognosis judgment of non-small cell lung cancer (NSCLC). CYFRA21-1 is often used to monitor the course and prognosis of non-small cell lung can...
