Background of Jurkat-NFAT-Luc2-CD3D-CD3E-KO-2A3-Cell-Line

The protein encoded by CD3D is part of the T-cell receptor/CD3 complex (TCR/CD3 complex) and is involved in T-cell development and signal transduction. The encoded membrane protein represents the delta subunit of the CD3 complex, and along with four other CD3 subunits, binds either TCR alpha/beta or TCR gamma/delta to form the TCR/CD3 complex on the surface of T-cells. Defects in this gene are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (SCIDBNK). The protein encoded by CD3E is the CD3-epsilon polypeptide, which together with CD3-gamma, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. The epsilon polypeptide plays an essential role in T-cell development. Defects in this gene cause immunodeficiency.

Cell Resuscitation

  1. Prewarm culture medium (RPMI1640 + 10% FBS+300μg/mL Hygromycin)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 1:4-1:6 every 2-3 days; seed out at about 1-3 × 105 cells/mL.

Cell Freezing

  1. Prepare the freezing medium (70% RPMI-1640 + 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
