Abstract:
The present invention discloses a mouse-human chimeric antibody preferably recognizes the MUC1 glycopeptide epitope RPAPGS(GalNAc)TAPPAHG (SEQ ID NO.: 34) on the surface of cancer cells, and the encoding sequences, wherein the monoclonal antibody having a light chain and a heavy chain. Moreover, the present invention provides humanized light and heavy chains, and the encoding sequences. The results of paired expression show that humanized antibodies also recognize the MUC1 glycopeptide epitope RPAPGS(GalNAc)TAPPAHG (SEQ ID NO.: 34) on the surface of cancer cells, and show the same specificity as the parental antibody.
