Abstract:Midkine (MK) is a heparin-binding growth factor and was found to be highly expressed in many types of human carcinomas. MK may become a novel tumor marker. In this study, we used the rabbit specific antibodies against human MK to establish a double antibody sandwich enzyme-linked immunosorbent assay (ELISA) of MK system and applied it to detect serum MK levels in different types of cancer patients. The standard curve, precision and recovery rate were tested, respectively, and serum MK concentration of 102 canc… Show more
