Background of BHK21-human-GIPR-High cell line

GIPR, also named as PGQTL2, is a G protein-coupled receptor that belongs to the 7-transmembrane protein family. GIPR is found on beta-cells in the pancreas where it serves as the receptor for the hormone Gastric inhibitory polypeptide. Diseases associated with GIPR include Adrenal Cortical Adenoma and Adrenal Adenoma. Among its related pathways are GPCR downstream signalling and Presynaptic function of Kainate receptor. Defects in this gene may contribute to the pathogenesis of diabetes.

Cell Resuscitation

1. Prewarm culture medium (70% DMEM supplemented with 10% FBS and 1μg/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 1:10 every 3 days; seed out at about 1-3 × 10⁵ cells/mL.

Cell Freezing

1. Prepare the freezing medium (70% 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.
