petosemtamab

Petosemtamab (MCLA 158) is a highly potent monoclonal antibody against EGFR (Kd: 0.22 nM) and LGR5 (Kd: 0.86 nM). Petosemtamab promotes EGFR signaling disruption and receptor breakdown in LGR5+ cancer cells. Petosemtamab can be used in the study of solid tumors such as head and neck squamous cell carcinoma (HNSCC) and metastatic colorectal cancer (CRC).

Petosemtamab (FUT8-KO) is a variant of Petosemtamab with the fucosyltransferase 8 gene (FUT8) knocked out. Petosemtamab is a monoclonal antibody (mAb) targeting EGFR (with a Kd of 0.22 nM) and LGR5 (with a Kd of 0.86 nM). This antibody disrupts EGFR signaling and causes receptor degradation in LGR5+ cancer cells. It is applicable in research on solid tumors such as head and neck squamous cell carcinoma (HNSCC) and metastatic colorectal cancer (CRC).
