Cofetuzumab
Based on 1 Customer Validation
Cofetuzumab (PF-06523435) is a humanized IgG1-κ monoclonal antibody targeting PTK7. The expression system of Cofetuzumab is typically CHO (Chinese hamster ovary) cells. Cofetuzumab downregulates PTK7 expression, modulates its downstream signaling pathways, and inhibits tumor sphere formation of ovarian cancer cells. Cofetuzumab can be used to synthesize the ADC molecule Cofetuzumab pelidotin (HY-P99829). Cofetuzumab is applicable to the research of tumors such as ovarian cancer.

Biological Activity
Human IgG1 kappa
Human
PTK7/CCK4
Cofetuzumab (10 μg/mL; 48 h) upregulates pERK1/2 in FIMM-PDC1-PDC3, and simultaneously upregulates ROR1 expression in FIMM-PDC3 with high PTK7 expression[1].
Cofetuzumab (10 μg/mL; 48 h) downregulates the expression level of SNCG protein in Kuramochi cells and FIMM-PDC1 cells[1].
Cofetuzumab (20 μg/mL; 5 days) inhibits tumor sphere formation and induces more dispersed structures in JHOS2, Kuramochi, FIMM-PDC3 and FIMM-PDC7 cells[1].
Cofetuzumab (10 μg/mL; 24 h) exerts synergistic cytotoxicity with Prexasertib (HY-18174) and Paclitaxel (HY-B0015) in FIMM-PDC3 cells[1].
