ADCC hPD-L1 Target Cell Line, Human Raji Cells (CAT#: AD-P007-C) Datasheet

PD-L1 (programmed cell death ligand 1; also known as CD274 or B7-H1) is a transmembrane protein expressed on the cell surface of hematopoietic and non-hematopoietic cells, induced by pro-inflammatory cytokines, such as in the tumor microenvironment in. PD-L1 is a ligand of PD-1, PD-1 is an inhibitory immune checkpoint receptor, expressed by activated and exhausted T cells. PD-1: PD-L1 interaction can induce the inhibition of T cell receptor signal transduction, thereby preventing T cell overstimulation and host damage.

Raji-hPD-L1 cells are developed from Raji cell line (a cell line derived from human B lymphocytes). Raji cells have been successfully used as target cells for CAR-T toxicity assays and human effect studies, such as antibody-dependent cytotoxicity (ADCC), which can be derived from peripheral blood mononuclear cells, natural killer (NK) cells or T cells Jurkat reporter cell.

Sterility Testing
Creative Biolabs provides sterility testing in accordance with USP and EP regulations. All of our sterility testing is performed in an isolator or clean room environments. The cell line has been screened using the membrane filtration testing methods to confirm the absence of aerobic, anaerobic and fungi microorganisms.
Identity Testing
Identity testing is required for newly established cell lines. Isoenzyme analysis is used to confirm the identity of the species of a cell line. Alternative methods for identity testing include DNA fingerprinting, STR analysis and karyology.
Virological Safety Testing
A broad range of viruses is susceptible to affecting human cell lines. We can provide in vivo/vitro virus saftey assays by utilizing various animal systems. These viruses include: adventitious viruses, bovine viruses, human and simian viruses, porcine viruses, retrovirus and rodent viruses.
Genetic Stability Testing
We perform cell genetic stability studies under ICH guidelines. We can provide guidance on the appropriate testing program upon your requirements.
Mycoplasma Testing
Guaranteed mycoplasma-free
Dry ice
-80°C for short-term storage, liquid nitrogen for long-term storage
Avoid multiple freeze/thaw cycles
Research Use Only
Our recombinant cell are for research use only, not for diagnostic or therapeutic use.
Quality Control
The expression of human PD-L1 has been verified by flow cytometry.
The induction of antibody-dependent cellular cytotoxicity (ADCC) has been verified using anti-hPD-L1-hIgG1 antibody and Jurkat-NFAT Lucia™ CD16 reporter cell line.
The stability of the 20 channels after thawing has been verified.
Raji-hPD-L1 cells are guaranteed to be free of mycoplasma.

Figure ADCC assay with Raji-hPD-L1 target cells
Incubate Raji-hPD-L1 cells with gradient concentrations of Anti-hPD-L1 or Anti-β-galactosidase (β-gal) mAb for 1 hour. Then the Jurkat NFAT-CD16 effector cells were incubated with the target cells for 6 hours. The activation of NFAT reflecting the induced ADCC response was evaluated by measuring Lucia luciferase activity in the supernatant using Luc. The percentage of maximum response normalized to the IgG1 isotype is shown.
