Raji/Human PD-L1 Stable Cell Line Development Service

For research use only.

描述(Description)

The Raji/Human PD-L1 Stable Cell Line was engineered to express full length human PD-L1 (Gene ID: 29126, used to mimic cancer target cells. When co-cultured with human PD-1 Reporter Cell, the PD-1/PD-L1 interaction inhibits TCR signaling and NFAT-mediated luminescence. Blocking the PD-1/PD-L1 interaction by either anti-PD-1 or anti-PD-L1 antibodies releases the inhibitory signal and results in TCR activation and NFAT-mediated luminescence.

Receptor Assay

PD-L1 FACS

Expression analysis of human PD-L1 on Raji/Human PD-L1 Stable Cell by FACS.
Raji/Human PD-L1 Stable Cell Line or negative control cell were stained with PE-labeled anti-human PD-L1 antibody.

Protocol

 

Application

PD-L1 APPLICATION

Blocking activity of anti-human PD-1 antibody (RLU).
This Raji/Human PD-L1 Stable Cell Line was incubated with serial dilutions of antibodies in the presence of reporter cells expressing human PD-1. The EC50 of anti-human PD-1 antibody was approximately 1.189 μg/mL.

Protocol

PD-L1 APPLICATION

Blocking activity of anti-human PD-1 antibody (FOLD).
This Raji/Human PD-L1 Stable Cell Line was incubated with serial dilutions of antibodies in the presence of reporter cells expressing human PD-1. The max induction fold was approximately 22.47.

背景(Background)

Programmed cell death 1 ligand 1 (PDL1) is also known as B7-H, B7H1, MGC142294, MGC142296, PD-L1, PDCD1L1 and PDCD1LG1,which is a member of the growing B7 family of immune molecules and is involved in the regulation of cellular and humoral immune responses.PDL1 is a cell surface immunoglobulin superfamily with two Ig-like domains within the extracellular region and a short cytoplasmic domain. This protein is broadly expressed in the majority of peripheral tissues as well as hematopoietic cells. Interaction between PDL1 and its receptors belonging to the CD28 family of molecules provide both stimulatory and inhibitory signals in regulating T cell activation and tolerance. PDL1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression.
