H_TNFRSF9(4-1BB) Reporter Jurkat Cell line
Description
Cat. No: GM-C09468
Product: H_TNFRSF9(4-1BB) Reporter Jurkat Cell line


4-1BB (CD137) is a protein in the TNF receptor superfamily, mainly found on T cells and NK cells. It is crucial for immune responses, enhancing T cell proliferation, survival, and function. Its activation is mediated by the ligand 4-1BBL (CD137L), expressed on activated dendritic cells, B cells, and some tumor cells. The signaling pathway involves TRAF and NF-κB, promoting cell survival and proliferation.

Activation of 4-1BB recruits TRAF2 and TRAF1, activating downstream pathways like NF-κB and MAPK, leading to cytokine production (e.g., IL-2 and IFN-γ). This enhances T cell immune responses, supporting anti-tumor immunity and infection clearance. Thus, 4-1BB is a key target in cancer immunotherapy, with potential as an immune checkpoint inhibitor.

H_TNFRSF9(4-1BB) Reporter Jurkat Cell line is a clonal stable cell line constructed using lentiviral technology, constitutive expression of the TNFRSF9(4-1BB) gene, along with signal-dependent expression of a luciferase reporter gene. When 4-1BBL binds to 4-1BB, it activates downstream signaling pathways, leading to the expression of luciferase. The luciferase activity measurement indicates the activation level of the signaling pathway and can thus be used to evaluate the in vitro effects of drugs related to TNFRSF9(4-1BB).

The maximum induction fold was approximately [27.1]. Data are shown by drug mass concentration.

GM-C09468) at a concentration of 1E5 cells/well (96-well format) was stimulated with serial dilutions of Human TNFSF9 / 4-1BBL / CD137L Protein (Sino Biological/15693-H01H) in assay buffer (RPMI 1640 + 1% FBS + 1% P.S) for 7 hours. The firefly luciferase activity was measured using the GMOne-Step 2.0 Luciferase Reporter Gene Assay Kit (Cat. GM-040513). The maximum induction fold was approximately [3.8]. The assay of Human CD40L / CD154 / TNFSF5 Protein is control group. Data are shown by drug mass concentration.
Response to Anti-H_4-1BB hIgG2 Antibody(Utomilumab). H_FCGR2B CHO-K1 Cell Line (Cat. GM-C21996) and CHO-K1 Cell Line were seeded at a density of 1.5E4 cells/well in a 96-well plate and incubated overnight. The next day, serial dilutions of the Anti-H_4-1BB hIgG2 Antibody(Utomilumab) (Cat. GM-26840AB) were incubated with 1E5 cells/well of the H_TNFRSF9(4-1BB) Reporter Jurkat Cell line (Cat. GM-C09468) in a 96-well plate, and then added to the pre-seeded cells. The mixture was incubated for an additional 6 hours. Firefly luciferase activity is then measured using the GMOne-Step 2.0 Luciferase Reporter Gene Assay Kit (Cat. GM-040513). The results indicated maximum blocking folds of approximately [193.3]. Data are shown by drug mass concentration.

Cell Culture

Cell Recovery

Recovery Medium: RPMI 1640 +10% FBS +1% P.S

To insure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C. Storage at -70°C will result in loss of viability.

a)       Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water. Thawing should be rapid (approximately 2 - 3 minutes).

b)       Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol. All of the operations from this point on should be carried out under strict aseptic conditions.

c)       Transfer the vial contents to a centrifuge tube containing 5.0 mL complete culture medium. And spin at approximately 176 x g for 5 minutes. Discard supernatant.

d)       Resuspend cell pellet with the recommended complete medium. And dispense the suspension into 1 - 2 T-25 culture flasks.

e)       Incubate the culture at 37°C in a suitable incubator. A 5% CO₂ in air atmosphere is recommended if using the medium described on this product sheet.

Cell Freezing

Freezing Medium: FBS+10% DMSO

a)          Centrifuge at 176 x g for 3 minutes to collect cells.

b)         Resuspend the cells in pre-cooled freezing medium and adjust the cell density to 5E6 cells/mL.

c)          Aliquot 1 mL into each vial.

d)         Place the vial in a controlled-rate freezing container and store at -80°C for at least 1 day, then transfer to liquid nitrogen as soon as possible.

Cell passage

Growth medium: RPMI 1640 +10% FBS +1% P.S +3.5 μg/mL Blastincidin+0.75 μg/mL Puromycin

Approximately 48-72 hours after the initial thawing, the cells can be passaged for the first time. After this initial passage, the culture medium can be adjusted to growth medium supplemented with antibiotics. If cells are not passaged within 48 hours, it is recommended to add some fresh recovery medium and place the flask horizontally.

a)          When the cell density reaches 1.5 - 2E6 cells/mL, subculture the cells. Do not allow the cell density to exceed 2E6 cells/mL.

b)         It is recommended to use T-25 flasks for subculturing.

c)          These cells are suspension cells, and it is recommended to use the "half-medium change" method to maintain optimal cell conditions during passaging.

d)         During passaging, you can directly add fresh growth medium to the culture flask, gently pipette to resuspend the cells, and then transfer the cell suspension to a new T-25 flask for continued culture.

Subcultivation Ratio: Maintain cultures at a cell concentraion between 3E5 and 1E6 viable cells/mL.

Medium Renewal: Every 2 to 3 days

Notes

a)          These cells are sensitive to density, so please ensure that the cell density is maintained within an appropriate range during culture and subculturing.

b)         During the first passage, pay attention to the nutrient supply; if not subculturing, make sure to add fresh recovery medium every other day as needed.
