Abstract
Disclosed is a monoclonal antibody that binds to human IL-5. The monoclonal antibody that binds to human IL-5 has a good biological activity for inhibiting TF-1 cell proliferation induced by IL-5 and blocking the interaction between IL-5 and IL-5RA, has a different antigen epitope from the known anti-human IL-5 antibody, can be used for preparing drugs for treating diseases mediated by the over-expression of eosinophilic granulocytes (such as asthma), and has a good clinical application prospect.
