If you represent a commercial entity, please contact us for alternative pricing.The HEK293-TACD2 cell line is a stable recombinant HEK293 cell line engineered to express the TACD2 receptor at a medium-high level, approximately 10,000 molecules per cell. This cell line was developed using inscreenex's landing pad technology, which ensures precise and reproducible integration of the TACD2 gene at a specific, pre-validated genomic locus. TACD2, also known as TROP2 or GA733-1, is a tumor-associated calcium signal transducer that plays a key role in intracellular calcium signaling, crucial for cellular processes such as growth, division, and differentiation. Overexpression of TACD2 has been observed in various carcinomas, including colorectal, gastric, and pancreatic cancers, making it a significant target for antibody-drug conjugates and immunotherapy.The expression of TACD2 in this cell line was confirmed using flow cytometry with a target-specific antibody, ensuring reliable and consistent receptor density across the cell population.

Receptors expressed: TACD2 (TROP2 or GA733-1)
- cultureMedium: RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a)
- supplements: Supplement the medium with 10% FBS, 1 mM sodium pyruvate, 10 mM HEPES, 1% NEAA. Add Geneticin (G418-Sulfat) to achieve a final concentration of 1 mg/mL.
- dissociationReagent: Trypsin-EDTA
- subculturing: For routine adherent cell culture: Aspirate the old culture medium from the adherent cells, and wash them with PBS to remove any remaining medium. After aspirating the PBS, add the appropriate volume of Trypsin/EDTA solution based on the culture vessel size (e.g., 1 ml for a T25 flask, 3 ml for a T75 flask) and incubate at room temperature or 37°C until the cells detach (5-10 minutes). Monitor detachment under a microscope, and gently tap the vessel if necessary to release the cells. Once detached, add complete medium to inactivate the Trypsin/EDTA, gently resuspend the cells, and transfer an aliquot of the cell suspension into a new culture vessel containing fresh medium. Place the vessel in an incubator set to 37°C with 5% CO2, and change the medium every 2-3 days.
- fluidRenewal: 2 to 3 times per week
- postThawRecovery: After thawing, split the cells at a ratio of 1:2 to 1:3 in T25 flasks and allow the cells to recover from the freezing process and to adhere for at least 24 hours.For best attachment and viability after thawing the cells, we recommend using Collagen-coated flasks or plates for the initial seeding after cryo-recovery. Collagen coating is not required for subsequent routine culture of the cells.
- freezeMedium: As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
