  • ANTIBODY AGAINST SECRETED N-TERMINAL PEPTIDE OF GPC3 PRESENT IN BLOOD OR C-TERMINAL PEPTIDE OF GPC3
    Publication number: 20200181248
    Abstract: Disclosed is an antibody against a secreted form of GPC3 capable of detecting a secreted form of glypican 3 (GPC3) in a test sample. It is possible to determine whether a subject suffers from cancer, in particular hepatoma. Also disclosed is an antibody against GPC as well as a cell disrupting agent and an anti-cancer agent comprising the same, which can disrupt cells, in particular cancer cells.
