Abstract

The invention provides a liver cancer metastasis prognosis quantitative antibody chip and a reagent kit. The quantitative prognosis chip comprises a substrate, specific antibodies, positive control and negative control. The specific antibodies of cancer related proteins are dispensed on the substrate. The liver cancer metastasis prognosis quantitative antibody is characterized in that the cancer related proteins include OPN (osteopontin), ICAM (intercellular cell adhesion moleculars), VEGF (vascular endothelial growth factors), MMP (matrix metal proteinase) 9, IL (interleukin) -8 and E-selectin. The reagent kit consists of the quantitative antibody chip adopting the OPN, the ICAM, the VEGF, the MMP9, the IL-8 and the E-selectin as detection objects, an antigen protein calibrator comprising OPN, ICAM, VEGF, MMP9, IL-8 and E-selectin and a biotinylated monoclonal detecting antibody comprising OPN, ICAM, VEGF, MMP9, IL-8 and E-selectin. The liver cancer metastasis prognosis quantitative antibody chip is successfully created, prognosis accuracy achieves 83% when the liver cancer metastasis prognosis quantitative antibody chip is applied to prognosis of liver cancer metastasis, and the liver cancer metastasis prognosis quantitative antibody chip and the reagent kit have an important clinical significance for judging prognosis of liver cancer patients.

Description

technical field [0001] The invention relates to a liver cancer metastasis prediction quantitative antibody chip and a kit, which belong to the fields of biotechnology and medical technology. Background technique [0002] Liver cancer is a malignant tumor with a very high degree of malignancy and a very poor prognosis. About half of the world's liver cancer patients are concentrated in China, and its fatality rate ranks second among all tumors in my country. Liver cancer is the second leading cause of cancer death in my country, and more than 50% of primary liver cancers in the world occur in my country. The high postoperative recurrence rate of metastasis (5-year recurrence rate reaches 70%, small liver cancer also reaches 50%) has become a bottleneck to further improve long-term efficacy, and is also an important key to conquer liver cancer. [0003] In recent years, with the in-depth research in basic medical fields such as immunology, molecular biology and biochemistry,...
