HUMAN ANTI-EPIDERMAL GROWTH FACTOR RECEPTOR SINGLE-CHAIN ANTIBODIES

摘要

Human anti-epidermal growth factor receptor (EGFR) single-chain antibodies (scFvs) were isolated from a human IgM phage display library using purified epidermal growth factor receptor as antigen. Two isolates with different ami no acid sequences were identified by ELISA as epidermal growth factor receptor- specific. the scFvs bind to the full length epidermal growth factor receptor and the truncated and/or mutated epidermal growth factor receptor on human cells. These anti-EGFR-scFvs are useful as therapeutic and/or diagnostic agents.
