Functional Assay
Application Notes
Monitor the STAT4 signaling pathway activity. Screen for activators or inhibitors of the STAT4 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 3 ug/ml of Puromycin. 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, spin down cells, resuspend cells in pre-warmed growth medium without Puromycin, 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. 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 STAT4 Leeporter- HEK293 cells to interferon gamma (Figure 1). 1. Harvest STAT4 Leeporter- HEK293 cells and seed cells into a white solid-bottom 96-well microplate in 100 ul of growth medium at 5 x 104 cells/well. 2. Incubate cells at 37 degree C in a CO2 incubator for overnight. 3. The next day, stimulate cells with different concentrations of IFN-gamma. 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 STAT4 cell line
The STAT4 Leeporter cell line is a stably transfected HEK 293 cell line which expresses Renilla luciferase reporter gene under the transcriptional control of the STAT4 responsive promoter, so that the cell line is designed to measure the transcriptional activity of STAT4. Signal Transducer and Activator of Transcription 4 (STAT4) is a member of the STAT transcription factor family and plays a central role in generating inflammation during protective immune responses and immune-mediated diseases.

NCBI Description
The protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is essential for mediating responses to IL12 in lymphocytes, and regulating the differentiation of T helper cells. Mutations in this gene may be associated with systemic lupus erythematosus and rheumatoid arthritis. Alternate splicing results in multiple transcript variants that encode the same protein.

Researchers should empirically determine the suitability of the STAT4 stat4 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 "STAT4, 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
