Abstract
The invention provides an antibody and/or an antigen binding fragment that binds to NGF, and the amino acid sequences of the heavy chain and light chain variable regions of the antibody. The NGF antibody and/or its antigen binding fragment provided by the invention has high affinity for NGF and can effectively block the binding between NGF receptor and NGF. This antibody and/or its antigen binding fragment can inhibit the binding activity of NGF and its receptor in vitro, and is suitable for the treatment of pain diseases which are related to the haughty expression or increased expression of NGF.
