Description
The CHO/ Human PD-L1 Stable Cell Line was engineered to express full length human PD-L1 receptor (Gene ID: 29126), 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 (Luc) HEK293 Reporter Cell (Cat.No.CHEK-ATF073) 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.
