CHO/Human PD-L1 Stable Cell Line (Medium Expression)

• Genetically modified cell lines best reflect MOA (Mechanism of Action)
• Higher activity and larger assay window for robust and reproducible cell-based bioassay
• Comprehensive application data to support assay development and validation
• Full tracible record, stringent quality control and validated cell passage stability
• Parental cell line legally obtained from internationally recognized cell resource bank and commercially licensed
• Global commercial license assistance whenever regulatory filing is required

The CHO/ Human PD-L1 Stable Cell Line was engineered to express the receptor full length human PD-L1 (Uniprot: Q9NZQ7-1), with different levels of PD-L1 expression (High, Medium, Low), which can be used to mimic cancer target cells with various PD-L1 expression levels. When co-cultured with Human 4-1BB HEK293 Reporter Cell and anti-human 4-1BB/PD-L1 BsAb, the anti-human 4-1BB/PD-L1 BsAb can be crosslinked, thereby strengthening 4-1BB pathway-activated luminescence.

• Useful for cell-based PD-L1 binding assay

• Useful for PD-L1-mediated crosslinking in reporter gene assay
