Anti-human P-cadherin (CDH3) recombinant antibody |
摘要 |
It is an object to provide a recombinant antibody that is an anti-CDH3 antibody having cytotoxicity on CDH3-expressing cells, which is anticipated to have fewer side effects than antibodies derived from animals other than humans and to maintain its therapeutic effects for a long period of time. The present invention provides a recombinant antibody which specifically reacts with an epitope existing in the amino acids at positions 108 to 131 or at positions 551 to 654 of the amino acid sequence shown in SEQ ID NO: 38 that is the extracellular region of human CDH3, and has cytotoxicity against CDH3-expressing cells. |

1. A recombinant antibody which specifically reacts with an epitope existing in the amino acids at positions 551 to 654 of the amino acid sequence shown in SEQ ID NO: 38 that is the extracellular region of human CDH3, and has cytotoxicity against CDH3-expressing cells, and which comprises the CDR1, CDR2 and CDR3 of a heavy chain variable region (HV), respectively, consisting of the amino acid sequences shown in SEQ ID NOS: 25-27, and the CDR1, CDR2 and CDR3 of a light chain variable region (LV), respectively, consisting of the amino acid sequences shown in SEQ ID NOS: 28-30. |
