The iNOS reporter cell line is a stably transfected RAW264.7 cell line which expresses Renilla luciferase reporter gene under the transcriptional control of the iNOS promoter. Inducible nitric oxide synthase (iNOS) is an inducible enzyme that catalyzes the production of nitric oxide (NO) from L-arginine. NO is one of the smallest signaling molecules that can diffuse into the cell and is involved in various physiological functions, pathogenesis of septic shock, many diseases associated with autoimmunity, and  tumorigenesis. iNOS gene is generally known to be induced by various proinflammatory cytokines and pathogen-associated molecular patterns such as TLR ligands. The iNOS induction by various Toll-like receptor (TLR) ligands as well as  phorbol 12-myristate 13-acetate 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.

Application:

  •  Monitor the JAK/STAT signaling pathway activity.
  • Screen for activators or inhibitors of the JAK/STAT signaling pathway. 


Culture conditions:

Cells should be grown at 37oC with 5% CO2 using DMEM medium supplemented with 10% FBS and 1% Pen/Strep, plus 3 µg/ml of Puromycin.
 
 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, spin down cells, resuspend cells in pre-warmed growth medium without Puromycin, 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. 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.


Functional validation:

A. Response of ISRE Leeporter™ – HEK293 cells to IFN-alpha.

1. Harvest 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 IFN-alpha. 
 
4. Incubate at 37oC in a CO2 incubator for 6 hours.
 
5. Add 50 µl of  luciferase assay reagent (Abeomics, Cat #17-1101) per well. 
 
6. Incubate at room temperature for 1-5 minutes and measure luminescence using a microplate luminometer.
