Embodiment 1

[0027] Example 1 Relationship between SYT12 autoantibodies in plasma and lung cancer 1. Clinical data

[0028] Select 30 cases of lung cancer patients, 29 cases of benign lung diseases (tuberculosis, hamartoma and other non-malignant tumors), and 29 cases of healthy controls. The basic information is as follows:

[0029]

[0030] 2. Detection principle

[0031] HuProt TM SYT12 protein is immobilized on the human protein custom chip (the SYT12 protein used is a full-length protein, and the protein sequence number is Ensembl: ENSP00000434709). After incubation with serum, SYT12 autoantibodies (mainly including IgG and IgM antibodies, and some Other types of antibodies) will bind to it, wash to remove unbound antibodies and other proteins, and then detect with anti-human IgM fluorescently labeled secondary antibody (cy5-labeled, red) and anti-human IgG fluorescent secondary antibody (cy3-labeled, green) , the signal is read by a fluorescence scanner, and the strength of the ...

Abstract

The invention relates to the field of in vitro diagnostic reagents, in particular to an application of an SYT12 autoantibody detection reagent in preparation of a lung cancer screening kit. The invention finds for the first time that the autoantibody level of SYT12 protein in serum of a lung cancer patient is significantly higher than that of a healthy patient. The reagent for detecting an SYT12 protein autoantibody is used for preparing the lung cancer screening kit and effective screening of lung cancer can be realized.

Description

technical field [0001] The invention relates to the field of in vitro diagnostic reagents, in particular to the use of SYT12 autoantibody detection reagents in the preparation of lung cancer screening kits. Background technique [0002] Lung cancer is one of the most common malignant tumors in the world. Its morbidity and mortality are increasing year by year. Currently, the incidence rate ranks first in the world, which seriously threatens human health and life. [0003] Lung cancer is a disease that is good at concealment. It often shows clinical symptoms when the disease develops to an advanced stage. 70-80% of lung cancer patients are already in the middle or late stage when they are diagnosed with lung cancer symptoms. The best cure time, five-year survival rate is low. For patients with early lung cancer, timely treatment can greatly improve the 5-year survival rate and quality of life of the patients. Therefore, early diagnosis and effective screening of lung cancer...
