GC1118
GC1118 (GC-1118A) is a fully human anti-EGFR monoclonal antibody with binding affinity of 0.16 nM (KD) to EGFR. GC1118 displays potent inhibitory effects on high- and low-affinity EGFR ligand-induced signaling. GC1118 shows potent anti proliferative activity in KRAS wild-type and KRAS mutant cells. GC1118 can reach the tumor by crossing both BBB (blood-brain barrier) and BTB (brain-tumor barrier) and shows superior anti-tumor effects in various mice xenograft models. GC1118 can be used for the researches of cancer, such as colorectal cancer.

GC1118 (GC-1118A) (1 μg/mL, 24-120 h) shows potent anti proliferative activity in KRAS wild-type and KRAS mutant cells[1][4].
GC1118 (100 µM, 6 days) suppresses cell growth in PDCs of G096 and G022[2].
GC1118 (0.1-50 μg/mL, 2 h) blocks EGFR high- and low-affinity ligand-induced EGFR signaling in HCT8 cells[3].
GC1118 (0.005-100 μg/mL, 3 days) inhibits high- and low-affinity ligand-induced proliferation in HCT8 cells[3].
