Used in targeted cancer therapies, this antibody binds to phosphatidylserine, a lipid normally found inside cell membranes but exposed on the surface of tumor blood vessels and some cancer cells. By targeting this marker, it helps the immune system recognize and attack tumors. It has been investigated in clinical trials for cancers such as lung, prostate, and breast cancer. Additionally, it has shown potential in treating viral infections by modulating immune responses and enhancing clearance of infected cells. Its mechanism supports combination therapies with chemotherapy, radiation, and other immunotherapies to improve treatment outcomes.
