Abstract

The invention relates to a kit. The kit adopts a gene recombinant Renilla and multi-antigen fusion protein to detect an autoimmune antibody in serum, which is related to the breast cancer, has high sensitivity and specificity, provides basis for diagnosis of the breast cancer, and provides scanning conditions for further pathological diagnosis. The kit is rapid and convenient to detect, accurate in detection result and harmless for a patient, has no radio-immunity pollution, can meet requirements of clinical diagnosis and particularly requirements of primary health care institutions and community general practitioners, and has wide market prospect.

Description

technical field [0001] The invention relates to a kit, in particular to a breast cancer autoimmune antibody detection kit that is fast and convenient to detect, has accurate detection results, does no harm to patients and has no radioimmune pollution, and can meet the needs of clinical diagnosis, as well as its preparation method and application . Background technique [0002] At present, the detection kits related to detection of breast cancer on the market generally detect tumor markers such as antigens, susceptibility genes, tumor suppressor genes, and epidermal growth factor receptor-2 (Her-2), etc., as follows: [0003] Carcinoembryonic antigen (CEA), ferritin, monoclonal antibody CA (CA153, CA549), epidermal growth factor receptor-2 (Her-2), estrogen, progesterone, estrogen receptor and progesterone receptor (ER , PR), epithelial growth factor receptor (EGFR), tumor suppressor gene P53, susceptibility genes BRCA1, BRCA2, autoantibody MMP-7, IGBR, CD117, BCL-2, PCNA, e...
