HEK-Blue™-hNOD1 cells were obtained by co-transfection of the human NOD1 gene and an optimized secreted embryonic alkaline phosphatase (SEAP) reporter gene into HEK293 cells.

The SEAP reporter gene is placed under the control of the IFN-β minimal promoter fused to five NF-κB and AP-1 binding sites. Stimulation with a NOD1 ligand activates NF-κB and AP-1 which induce the production of SEAP. 

Levels of SEAP can be easily determined with HEK-Blue™ Detection, a cell culture medium that allows for real-time detection of SEAP.

The parental cell line of HEK-Blue™ hNOD1 cells is HEK-Blue™ Null1 cells.

Response of HEK-Blue™ hNOD1 cells to TLR and NOD agonists

HEK-Blue™ hNOD1 cells were stimulated with various TLR and NOD agonists: Pam3CSK4 (100 ng/ml), Poly(I:C) (50 ng/ml), LPS-EB ultrapure (100 ng/ml), recombinant flagellin from S. typhimurium (10 ng/ml), CL264 (1 µg/ml), CL097 (3 µg/ml), ssRNA40/LyoVec™ (5 µg/ml), ODN 2006 (10 µg/ml), C12-iE-DAP (100 ng/ml), L18-MDP (100 ng/ml), and TNF-α (100 ng/ml). After 18h incubation (24h incubation for CL264, C12-iE-DAP and L18-MDP ligands), NF-κB-induced SEAP activity was assessed using QUANTI-Blue™ and reading the OD at 655 nm.


HEK-Blue™ hNOD1 and HEK-Blue™ Null1 (control) cells were incubated in HEK-Blue™ Detection medium and stimulated with 100 ng/ml C12-iE-DAP (NOD1), 1 µg/ml M-TriDAP (NOD1/2), 1 µg/ml Tri-DAP (NOD1), or 1 µg/ml iE-DAP (NOD1). After 24h incubation, the levels of NF-κB-induced SEAP were determined by reading the OD at 655 nm.

NOD1 agonists dose response
NOD1 agonists dose response

HEK-Blue™ hNOD1 cells were incubated in HEK-Blue™ Detection medium and stimulated with increasing concentrations of NOD1 agonists. After 24h incubation, the levels of NF-κB-induced SEAP were determined by reading the OD at 655 nm. The response ratio was calculated by dividing the OD at 655 nm for the treated cells by the OD at 655 nm for the untreated cells.

Ligand EC50 Response Ratio
 C12-iE-DAP 5 +/- 2 ng/ml 10
 Tri-DAP 700 +/- 100 ng/ml 6
iE-DAP 6.3 +/- 0.5 µg/ml 5
