Hematopoietic progenitor kinase (HPK1) is a member of a family of mitogen-activated protein kinase kinase kinase kinase (MAP4K) of Ste20 serine/threonine kinases, which is predominantly expressed in hematopoietic cells and has been shown to be a negative immune regulator of T-cell receptor (TCR) and B-cell signaling.

Characterization using PCR sequencing and WB




Cell Resuscitation

1. Prewarm culture medium (RPMI1640 + 10%FBS) 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
