| abstract |
An EGFR antibody, a preparation method therefor and an application thereof. The antibody comprises a complementary determining region (CDR): one or more of a heavy chain CDR1, a heavy chain CDR2, or a heavy chain CDR3, and/or one or more of a light chain CDR1, a light chain CDR2, or a light chain CDR3 of the EGFR antibody. The EGFR antibody has a high affinity to EGFR proteins and a cytotoxic killing effect to EGFR positive cells, and thus can be applied to the preparation of drugs for treating tumors and the like. |
