for tumour detectionfor gastrointestinal diseasesprotease

the cysteine protease inhibitor family plays an important role in tumor formation, invasion, metastasis and development. [1,2] Cysteine protease inhibitor S (c S t4) belongs to the type ii cysteine protease family and is encoded by 16 soluble secreted proteins p11.21 chromosome 20. [3,4]Normal expression in saliva, tears, seminal plasma, serum CST4 expression content is low. CST4 protein is secreted by tumor cells in patients with gastric cancer, which can detect high concentrations of CST4 protein in serum of patients with gastric malignant tumor. Tumor cells secrete a large amount of CST4 protein, which can detect a high concentration of CST4 protein in the serum of intestinal tumor patients. [Intended use] The product is used for quantitative determination of cysteine protease inhibitor S (C S T4) in human serum in vitro. The results are mainly used for dynamic monitoring of gastrointestinal tumor patients to assist in judging the disease process or therapeutic effect. [Product Advantage] The first gastrointestinal cancer early diagnosis of new signs. The clinical diagnostic performance is far more than CEA TM. Monitoring gastrointestinal cancer changes. Early detection rate 40-60%, specificity 90%. As the only reliable "early gastrointestinal" at present Cancer Indicators, it shows great advantage in repeatability, reliable detection, simple equipment and convenient operation.
