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 (w/ L-Glutamine, 4.5g/L Glucose and Sodium Pyruvate) supplemented with 10% heat-inactivated FBS and 1% Pen/Strep, plus 3 µg/ml of Puromycin (Note: Puromycin 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, 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 1~2 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. Note: RAW264.7 cells may not be detached well by trypsinization only. So you may need to use a cell scraper to harvest the trypsinized cells.
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 ISRE Leeporter™ – RAW264.7 cells to poly(I:C).
1. Plate ISRE Leeporter™ – RAW264.7 cells into a white solid-bottom 96-well microplate in 100 ul of growth medium at 1 x 105 cells/well and incubate cells at 37oC in a CO2 incubator for 4-6 hours.
2. Stimulate cells with different concentrations of poly(I:C) and incubate cells at 37oC in a CO2 incubator for 16 hours. ,
3. Equilibrate the plate to room temperature for 10 minutes.
4. Add 50 µl of luciferase assay reagent (Abeomics, Cat #17-1101; Refer to the reagent datasheet for the detailed luciferase assay protocol) per well.
5. Read the plate in 1-5 minutes to measure luminescence using a microplate luminometer.
