    摘要: Cysteine engineered monospecific and bispecific EGFR and/or c-Met FN 3 domain containing molecules comprising one or more free cysteine amino acids are prepared by mutagenizig a nucleic acid sequence of a parent molecule and replacing one or more amino acid residues by cysteine to encode the cysteine engineered FN3 domain containing monospecific or bispecific molecules; expressing the cysteine engineered FN3 domain containing molecules: and recovering the cysteine engineered FN3 domain containing molecule. Isolated cysteine engineered monospecific or bispecific FN3 domain containing molecules may be covalently attached to a detection label or a drug moiety and used therapeutically.
