Applicable Applications for TLR4/IL-8 cell line
Functional Assay
Application Notes
Monitor the TLR4 signaling pathway activity. Screen for activators or inhibitors of the TLR4 signaling pathway. Culture conditions: Cells should be grown at 37 degree C with 5% CO2 using DMEM medium supplemented with 10% FBS and 1% Pen/Strep, plus 1 ug/ml Puromycin, 5 ug/ml blasticidin and 500 ug/ml G418. It is recommended to quickly thaw the frozen cells upon receipt or from liquid nitrogen in a 37 degree C water-bath, transfer to a tube containing 10 ml of growth medium without Puromycin, Blasticidin and G418, spin down cells, resuspend cells in pre-warmed growth medium without Puromycin, Blasticidin and G418, transfer resuspended cells to T25 flask and culture in 37 degree C-CO2 incubator. Leave the T25 flask in the incubator for 2~4 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, Blasticidin and G418. 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 TLR4/IL-8 Leeporter- HeLa cells to LPS. 1. Harvest TLR4/IL-8 Leeporter- HeLa cells and seed cells into a white solid-bottom 96-well microplate in 100 ul of growth medium at 5 x 10^4 cells/well. 2. Incubate cells at 37 degree C in a CO2 incubator for overnight. 3. The next day, stimulate cells with various concentrations of LPS. 4. Incubate at 37 degree C in a CO2 incubator for 6-16 hours. 5. Add 30-50 ul of luciferase assay reagent per well. 6. Incubate at room temperature for 1-5 minutes and measure luminescence using a microplate luminometer.

Related Product Information for TLR4/IL-8 cell line
The TLR4/IL-8 Leeporter cell line is a stably transfected HeLa cell line which expresses human TLR4, MD-2 and CD14 as well Renilla luciferase reporter gene under the transcriptional control of the IL-8 promoter. IL-8 is one of the major pro-inflammatory cytokines induced by ligand (such as LPS)-mediated Toll-like receptor 4 (TLR4) activation. TLR4 is one of the key innate immune receptors, which is activated by LPS and can lead to sepsis upon dysregulation.

Researchers should empirically determine the suitability of the TLR4/IL-8 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "TLR4/IL-8, Cell Line" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
