The PD-1/PD-L2 Inhibitor Screening Cell-Based Assay is a bioluminescent cell-based assay that can be used to screen and profile inhibitors of the PD-1:PD-L2 interaction. The assay consists of two main components: • Growth-Arrested PD-1 Effector cells (PD-1/NFAT reporter-Jurkat cells): Reporter Jurkat T cells expressing firefly luciferase gene under the control of NFAT response elements and also constitutively expressing Human PD-1. These cryopreserved cells are provided in a thaw-anduse format that does not require cell propagation. These cells are modified not to be expanded and are intended to be used in a single experiment. • Expression vectors for TCR activator and Human PD-L2: Transfection-ready vectors are used to transfect cells to create the target cells that overexpress PD-L2 and an engineered cell surface T cell receptor (TCR) activator.

Recombinant Jurkat T cell expressing firefly luciferase gene under the control of NFAT response elements with constitutive expression of human PD-1 (Programmed Cell Death 1, PDCD1, SLEB2, CD279, GenBank Accession #NM_005018). Note: These cells are unable to complete mitosis and are suitable for single use assays. For cells capable of reproducing, please use our PD-1 / NFAT Reporter - Jurkat Recombinant Cell Line, #60535.

Recombinant CHO-K1 cells constitutively expressing both the human BCMA protein (B-Cell Maturation Antigen or CD269, GenBank accession #NM_001192) and the Gaussia Luciferase (Δ Signal peptide). Surface expression of BCMA was confirmed by flow cytometry.

Cryopreserved vial (30 x 10^6 cells) of freshly isolated primary human peripheral blood mononuclear cells (PBMCs) from a healthy donor, isolated from leukapheresis / apheresis samples using Ficoll gradient. After isolation, the PBMCs were stained to identify sub populations and evaluated for viability by flow cytometry. Cells were cryopreserved in serum-free Cryostor CS10 at a controlled rate.

N-terminal His-tagged human PDE1B has been stably expressed in HEK293 cell line and its expression was confirmed by Western blotting. The function of PDE1B was characterized by a cell-based cGMP assay. In this assay system, cells co-express atrial natriuretic peptide (ANP) receptor A (a guanylate cyclase), cyclic nucleotide5gated cation channel CNGA2, and the photoprotein aequorin. Intracellular cGMP level is monitored via aequorin luminescence induced by Ca²⁺ influx through CNGA2, acting as the intracellular cGMP sensor.

The AP-1 Reporter - HEK293 Cell Linee is designed for monitoring the activity of the JNK signaling pathway. The AP1 Reporter - HEK293 cell line contains a firefly luciferase gene under the control of AP1-responsive elements that are stably integrated into HEK293 cells.

The SRE Reporter - HEK293 cell line is designed for monitoring the activity of the JAK/STAT signaling pathway. The SRE Reporter - HEK293 cell line contains a firefly luciferase gene under the control of SRE responsive elements stably integrated into HEK293 cells, resulting in an ERK pathway-responsive reporter cell line.

N-terminal FLAG-tagged human PDE7A has been stably expressed in a human embryonic kidney (HEK293) cell line. PDE7A expression was confirmed by Western blotting. The regulation of intracellular level of cAMP by PDE7A in PDE7A stably-expressed HEK293 cells was characterized by a cell-based reporter assay using pCRE-luc reporter vector. pCRE-luc contains a luciferase gene that is under the control of the cAMP response element (CRE). When cells transiently transfected with pCRE-luc reporter were activated by forskolin, the level of cAMP was upregulated in parental HEK293 cells, inducing the expression of the luciferase reporter, whereas hPDE7A-HEK293 cells showed reduction in the level of cAMP that resulted in lowered expression of luciferase.
