The invention discloses an anti-human GPC3
monoclonal antibody which is a specific high-affinity nanometer
antibody developed by using human GPC3 as a target on the basis of a
phage display technology. Compared with the prior art, the anti-human GPC3
monoclonal antibody is successfully prepared; the antibody has high specificity and high affinity, and can be combined with the human GPC3 expressedon the
cell surfaces; and the anti-human GPC3
monoclonal antibody belongs to potential
medicine for tumor
immunotherapy.
