Background of RENCA-CAIX Cell Line

CA9 (Carbonic Anhydrase 9) is a Protein Coding gene. Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and in their subcellular localization. CA IX is a transmembrane protein and is one of only two tumor-associated carbonic anhydrase isoenzymes known. It is expressed in all clear-cell renal cell carcinoma, but is not detected in normal kidney or most other normal tissues. It may be involved in cell proliferation and transformation. This gene was mapped to 17q21.2 by fluorescence in situ hybridization, however, radiation hybrid mapping localized it to 9p13-p12.

Cell Resuscitation

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

Cell Freezing

Prepare the freezing medium (70% RPMI1640 + 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.
