Background of HEK293T-ARV7-Cell-Line

ARv7, also known as AR3. As the most common AR-V, the androgen receptor splice variant 7 (AR-V7), a splice variant of the androgen receptor mRNA resulting in the truncation of the ligand-binding domain, is a promising predictive tumor marker and a relevant selection marker for the treatment of advanced prostate cancer.

Cell Line Generation

HEK293 human ARv7 cell line was generated using a lentiviral vector expressing the human ARv7 sequence.

Characterization

Cell Resuscitation

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

Cell Freezing

Prepare the freezing medium (70% DMEM + 20% FBS + 10% DMSO) fresh immediately before use.
Keep the freezing medium on ice and label cryovials.
Transfer cells to a sterile, conical centrifuge tube, and count the cells.
Centrifuge the cells at 250×g for 5 minutes at room temperature and carefully aspirate off the medium.
Resuspend the cells at a density of at least 3×10⁶ cells/mL in chilled freezing medium.
Aliquot 1 mL of the cell suspension into each cryovial.
Freeze cells in the CoolCell freezing container overnight in a -80°C freezer.
Transfer vials to liquid nitrogen for long-term storage
