Leukocyte Migration Inhibition Assay in Patients with Bladder Cancer

Abstract
The leukocyte migration inhibition assay has successfully demonstrated tumor-associated antigenic activity in protein extracts of cell culture lines of a number of neoplasms. A high degree of leukocyte migration inhibition reactivity was shown in protein extracts from the well-characterized T-24 transitional [human bladder] carcinoma cell line. The leukocyte migration inhibition assay may be a valuable method of in vitro assessment of the cell-mediated immunity of bladder cancer patients and as a method to monitor attempts at further purification of tumor-associated antigens.
