Background of 293T-rat-GIPR Cell Line

Human ortholog(s) of GIPR implicated in cardiovascular system disease; diabetes mellitus; and obesity. Orthologous to human GIPR (gastric inhibitory polypeptide receptor). Enables gastric inhibitory peptide receptor activity and peptide hormone binding activity. Involved in several processes, including desensitization of G protein-coupled receptor signaling pathway; gastric inhibitory peptide signaling pathway; and positive regulation of insulin secretion.

Cell Resuscitation

Prewarm culture medium (DMEM supplemented with 10% FBS and 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 1:4-1:8 every 2-3 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.
