The TLR3/IFNB reporter cell line is a stably transfected HEK 293 cell line which expresses full-length human Toll-like receptor 3 (TLR3) and Renilla luciferase reporter gene under the transcriptional control of the interferon stimulated response element (ISRE). Functional activity of the cell line has been validated by TLR3 ligand assay (Figure 1), in which upon activation by poly (I:C), TLR3 quickly initiates TRIF-dependent signaling pathway and mediates nuclear translocation of IRF3 that induces ISRE activity.The TLR3/ISRE activation by poly(I:C) is shown in Figure 1. 

Content : Each vial contains 2 ~ 3 x 10^6 cells in 1 ml of 90% FBS + 10% DMSO.
Storage condition : Immediately upon receipt, store in liquid nitrogen.


  • Monitor the TLR3 signaling pathway activity.
  • Screen for activators or inhibitors of the TLR3 signaling pathway. 

Culture conditions:

Cells should be grown at 37oC with 5% CO2 using DMEM medium (w/ L-Glutamine, 4.5g/L Glucose and Sodium Pyruvate) supplemented with 10% heat-inactivated FBS and 1% Pen/Strep, plus 2 µg/ml of Puromycin and 5 µg/ml Blasticidin (Note: Puromycin Blasticidin can be omitted during the reporter cell assays).
 It is recommended to quickly thaw the frozen cells upon receipt or from liquid nitrogen in a 37oC water-bath, transfer to a tube containing 10 ml of growth medium without Puromycin and Blasticidin, spin down cells, resuspend cells in pre-warmed growth medium without Puromycin and Blasticidin, transfer resuspended cells to T25 flask and culture in 37oC-CO2 incubator.
Leave the T25 flask in the incubator for 1~3 days without disturbing or changing the medium until cells completely recover viability and become adherent. Once cells are over 90% adherent, remove growth medium and passage the cells through trypsinization and centrifugation. At first passage, switch to growth medium containing Puromycin and Blasticidin. Cells should be split before they reach complete confluence.

To passage the cells, detach cells from culture vessel with Trypsin/EDTA, add complete growth medium and transfer to a tube, spin down cells, resuspend cells and seed appropriate aliquots of cells suspension into new culture vessels. Subcultivation ration = 1:10 to 1:20 weekly. To achieve satisfactory results, cells should not be passaged over 16 times.

Functional validation:

A. Response of TLR3/ISRE Leeporter™ – HEK293 cells to Poly(I:C).

1. Harvest TLR3/ISRE Leeporter™ – HEK293 cells and seed cells into a white solid-bottom 96-well microplate in 100 µl of growth medium at 5 x 10^4 cells/well. 
2. Incubate cells at 37oC in a CO2 incubator for overnight.
3. The next day, stimulate cells with various concentrations of poly(I:C).
4. Incubate at 37oC in a CO2 incubator for 16 hours.
5. Equilibrate the plate to room temperature for 10 minutes. 
6. Add 50 µl of  luciferase assay reagent (Abeomics, Cat #17-1101; Refer to the reagent datasheet for the detailed luciferase assay protocol) per well. 
7. Read the plate in 1-5 minutes to measure luminescence using a microplate luminometer.
