Necitumumab
Based on 1 Customer Validation
Necitumumab (11F8; IMC-11F8; LY3012211) is a human IgG monoclonal antibody directed against EGFR. Necitumumab binds to the EGF binding site of EGFR, blocks ligand binding, neutralizes ligand-induced EGFR phosphorylation and downstream signaling, induces EGFR internalization and degradation, and mediates antibody-dependent cellular cytotoxicity (ADCC) in EGFR-expressing cells. Necitumumab enhances antitumour activity in combination with Gemcitabine (HY-17026) and Cisplatin (HY-17394) in murine non-small-cell lung cancer xenograft models. Necitumumab can be used in research on cancers such as non-small cell lung cancer and colorectal cancer.

Biological Activity
Human IgG1 kappa
Human
ERBB1/EGFR/HER1
Necitumumab specifically binds to the EGF binding site of human EGFR with high affinity (dissociation constant 0.32 nM) and blocks ligand binding with an IC50 of 1-2 nM[1].
Necitumumab neutralizes ligand-induced EGFR phosphorylation with an IC50 of 1.5-3 nM[1].
Necitumumab inhibits the proliferation of EGFR-dependent colorectal tumour cells with an IC50 of 0.8-1.0 nM[1].
Necitumumab induces EGFR internalization and degradation, and triggers antibody-dependent cellular cytotoxicity in EGFR-expressing human cells[1].
