Basic Information | |
Specificity | This antibody strongly binds human and cynomolgus monkey PD-L1 and shows weak binding for mouse PD-L1. PD-L1 is highly expressed in many human tumors. . PD-L1 exerts an immune suppressive signal through binding to PD-1 and B7.1, and tumor expression of PD-L1 can mediate cancer immune evasion. Blocking this pathway, therefore provides a rationale for cancer immunotherapy. |
Alternative Name | CD274; PDL1; B7-H1; B7H1; B7 homolog 1; hPD-L1; PDCD1L1; PDCD1LG1; PDCD1 ligand 1; Programmed cell death 1 ligand 1; Programmed death ligand 1 |
UniProt | Q9NZQ7 |
Immunogen | The original parental antibody 332M1 was generated by immunizing BALB/c mice with recombinant human PD-L1. Later on the humanized version of 332M1 was generated (332M7) by grafting the CDRs of the original mouse antibody onto human framework regions. |
Application Notes | The binding characterization of this antibody towards human, mouse and cynomolgus monkey PD-L1 was done using flow cytometry. This antibody was shown to block the binding of hPD-1-Fc protein to hPD-L1 expressed on the surface of the HEK-293T cells at a concentration of 10 μg/ml. The mouse version of this antibody was reported to inhibit patient derived melanoma tumor in tumor-bearing mice.There was also found an increase in the gene expression of CD8 and IFN-γ in tumor samples from mice treated with mouse version of this antibody (US20180346571). |
