osteopontin functional epitopes, monoclonal antibody against epitopes and uses thereof.

摘要

Provided are functional epitopes of osteopontin (OPN), monoclonal antibodies that specifically bind to the epitopes, immunoconjugates comprising the monoclonal antibodies and use of the monoclonal antibodies or immunoconjugates for manufacturing a medicament for the treatment of tumor. Also provided are nucleotide sequences encoding the monoclonal antibodies and vectors and host cells comprising the sequences. The monoclonal antibodies or immunoconjugates can be used for detecting the OPN, blocking the promoting metastasis-signaling pathway mediated by OPN and preventing the development and metastasis of tumor, thereby inhibiting the tumor.
