New humanized and chimeric monoclonal antibodies that recognize EGF-R and comprise an artificial sequence at least of the FRs of the heavy chain variable region of a human immunoglobulin. The hypervariable regions of both monoclonal antibodies is the following amino acid sequence:
light chain:
CDR-1: arg-ser-ser-gln-asn-ile-val-his-ser-asn-gly-asn-thr-tyr-leu-asp;
CDR-2: lys-val-ser-asn-arg-phe-ser;
CDR-3: phe-gln-tyr-ser-hys-val-pro-trp-thr.
Heavy chain:
CDR-1: asn-tyr-tyr-ile-tyr;
CDR-2: gly-ile-asn-pro-thr-ser-gly-gly-ser-asn-phe-asn-glu-lys-phe-lys-thr;
CDR-3: gln-gly-leu-trp-phe-asp-ser-asp-gly-arg-gly-phe-asp-phe.
Use of the antibodies for therapeutical and diagnostic purposes.
