Biological Information

  • Product Name
    Petosemtamab
  • Note
    Research use only, not for human use.
  • Brief Description
    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.
  • Description
    Petosemtamab (MCLA 158) is an anti- EGFR (Kd: 0.22 nM) and anti-LGR5 (Kd: 0.86 nM) monoclonal antibody (mAb). Petosemtamab leads to EGFR signaling blockade and receptor degradation in LGR5+ cancer cells. Petosemtamab can be used in the research of solid tumors, such as head and neck squamous cell carcinoma (HNSCC), metastatic colorectal cancer (CRC).
