Background of 293T-NFκB-Luc2-CD40 Cell Line

CD40, also named as TNFRSF5, is a transmembrane protein of the TNF receptor superfamily, expressed on B cells, DC cells, macrophage, monocytes and plates, CD40 functioned as a costimulatory molecule and mediated broad immune and inflammatory response.

Cell Line Generation

293T-NFκB-Luc2-CD40 Cell Line was generated using a lentiviral vector expressing the CD40 sequence.

Characterization

Figure 2: 293T-NFκB-Luc2-CD40 cell were seeded into 96-well plates, treated with Selicrelumab in different concentrations for 6 hours, and then read out using Bright-Glo Detection System.

Figure 3: 293T-NFκB-Luc2-CD40 cell were seeded into 96-well plates, treated with Recombinant Human CD40 Ligand/TNFSF5 in different concentrations for 6 hours, and then read out using Bright-Glo Detection System.

Figure 4: 293T-NFκB-Luc2-CD40 cells were seeded into 96-well plates, treated with COP-7657-hIgG1(Cat#KB-1587, Kyinno) or APB-A1-hlgG1(Cat#KB-1590, Kyinno) in different concentrations for 1 hours, and then treated with Recombinant Human CD40 Ligand/TNFSF5 in the concentration of 0.2μg/mL for 6 hours, and then read out using Bright-Glo Detection System."

Cell Resuscitation

  1. Prewarm culture medium (DMEM supplemented with 10% FBS, 0.5μg/mL Puromycin) in a 37°C water bath.
  2. Thaw the frozen vial in a 37°C water bath for 1-2 minutes.
  3. Transfer the vial into biosafety cabinet, and wipe the surface with 70% ethanol.
  4. Unscrew the top of the vial and transfer the cell suspension gently into a sterile centrifuge tube containing 9.0mL complete culture medium.
  5. Spin at ~ 125 × g for 5-7 minutes at room temperature, and discard the supernatant without disturbing the pellet.
  6. Resuspend cell pellet with the appropriate volume of complete medium and transfer the cell suspension into a T25 culture flask.
  7. Incubate the flask at 37°C, 5% CO2 incubator.
  8. Split saturated culture 1:4-1:5 every 2-3 days; seed out at about 1 × 105 cells/mL.

Cell Freezing

  1. Prepare the freezing medium (DMEM + 20% FBS + 10% DMSO) fresh immediately before use.
  2. Keep the freezing medium on ice and label cryovials.
  3. Transfer cells to a sterile, conical centrifuge tube, and count the cells.
  4. Centrifuge the cells at 250×g for 5 minutes at room temperature and carefully aspirate off the medium.
  5. Resuspend the cells at a density of at least 3×106 cells/mL in chilled freezing medium.
  6. Aliquot 1 mL of the cell suspension into each cryovial.
  7. Freeze cells in the CoolCell freezing container overnight in a -80°C freezer.
  8. Transfer vials to liquid nitrogen for long-term storage.
