A New Weapon For The War On Cancer


Engineered opsonin protein captures circulating tumor cells in the bloodstream with high efficiency

Wyss Institute for Biologically Inspired Engineering at Harvard
Scientists have adapted an engineered human blood opsonin protein known as FcMBL, which was originally developed as a broad-spectrum pathogen capture agent, to target circulating tumor cells — the notoriously rare and difficult-to-locate agents of metastasis. Using magnetic beads coated with FcMBL, they were able to capture >90 percent of seven different types of cancer cells, demonstrating that the approach could be valuable in cancer diagnostics and monitoring.
