TPS
TPS® – tissue polypeptide antigen specific assay determines soluble fragments of Cytokeratin 18, containing defined epitope recognized by antibody M3, in human serum. The size of the determined cytokeratin fragments is in the range of 10-500 kDa. The determination of TPS® can be used as an aid in monitoring and prognosis in patients with epithelial cell carcinoma, e.g. breast, prostate and ovarian cancer.
