Embodiment 1
[0035] Example 1, GSH-Px3 can be used as expression verification of breast cancer diagnostic markers
[0036] Using Western blotting method, 12% polyacrylamide gel was used, and 15ug of each serum sample was loaded. The primary antibody of GSH-Px3 was: glutathione peroxidase 3 mouse monoclonal antibody, which Dilute to 0.2μg / ml-0.5μg / ml with PBS buffer, preferably 0.2μg / ml; the secondary antibody used is: peroxidase goat anti-mouse IgG polyclonal antibody, which is diluted to 0.01μg / ml with PBS buffer ml - 0.02 μg / ml, preferably 0.02 μg / ml. from figure 1 and figure 2 In the study, it was found that the concentration of GSH-Px3 in the serum of breast cancer patients was higher than that of healthy controls, and the significance was analyzed by the expression of GSH-Px3 in serum between healthy people and breast cancer patients (T-text ), if the expression level of GSH-Px3 in the blood sample to be tested is compared with the expression level of GSH-Px3 in the serum of healt...
Embodiment 2
[0039] Embodiment 2, breast cancer diagnosis kit of the present invention
[0040] This embodiment provides a kit for breast cancer diagnosis, including an antibody that can bind, adsorb and / or couple to GSH-Px3.
[0041] Specifically, the antibodies include: glutathione peroxidase 3 primary antibody, specifically glutathione peroxidase 3 mouse monoclonal antibody, the advantages of using it as a primary antibody are: high sensitivity, specificity It has good sex and can detect glutathione peroxidase in human serum 3), the antibody also includes: a secondary antibody that recognizes the primary antibody, specifically a peroxidase goat anti-mouse IgG polyclonal antibody; the advantage is sensitivity High and specific, can bind glutathione peroxidase 3 primary antibody.
[0042] Preferably, the working concentration range of the primary antibody: 0.2 μg / ml-0.5 μg / ml; the working concentration range of the secondary antibody: 0.01 μg / ml-0.02 μg / ml.
[0043] Further, the kit als...
Embodiment 3
[0045] Embodiment 3, adopt kit described in the present invention to carry out breast cancer diagnosis
[0046] In the present embodiment, 11 blood samples of breast cancer patients were collected, and the kit of the present invention was used to diagnose breast cancer, and 9 of them were diagnosed with breast cancer, with a detection rate of 88.2%; 20 blood samples of healthy people were detected, GSH-Px3 content was normal.
[0047] Among the existing serological diagnostic methods for breast cancer in this field, the most commonly used detection method is the detection method (enzyme-linked immunosorbent assay) using CEA as a tumor marker. This method was used to detect the same 11 breast cancer patient blood samples above, and the results were Eight were found to have breast cancer.
[0048] The matching rate of the kit of the present invention and the conventional method is 89.9%.
