DAN-G Cells

Categories: Pancreas cancer cell lines Description: The DAN-G cell line is derived from a human pancreatic carcinoma. It is extensively utilized in research focused on pancreatic cancer, particularly in studies pertaining to tumorigenesis, metastasis, and chemotherapy resistance. The genetic profile of DAN-G includes mutations in key oncogenes and tumor suppressor genes, which are characteristic of pancreatic adenocarcinomas. This makes the cell line a valuable model for understanding the molecular mechanisms underlying pancreatic cancer and for testing new therapeutic strategies. In addition to its applications in cancer research, the DAN-G cell line has been used to study the cellular processes involved in the progression of pancreatic ductal adenocarcinoma, including cell cycle regulation, apoptosis, and signal transduction pathways. The cells exhibit aggressive in vitro growth characteristics and have the ability to form tumors in immunocompromised mice, which simulates the human disease and provides an in vivo system for evaluating the efficacy of anticancer drugs. Researchers also employ this cell line to investigate the role of the tumor microenvironment in pancreatic cancer progression and resistance to therapy. Organism: Human Tissue: Pancreas Disease: Adenocarcinoma Synonyms: Dan-G, DanG, DANG Age: 68 years Gender: Female Morphology: Epithelial-like Growth Properties: Adherent Citation: DAN-G (Cytion catalog number 300162) Biosafety Level: 1 Ncbi_ Taxid: 9606.0 Cellosaurus Accession: CVCL_0243 Protein Expression: p53 negative Tumorigenic: Yes, in nude mice Mutational Profile: DAN-G cells carry a homozygous Kras mutation in codon12: GGT(Gly) >GTT(Val) Culture Medium: 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 Dissociation Reagent: Accutase Doubling Time: 33 hours Subculturing: Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium. Seeding Density: 3 to 4 x 104 cells/cm2 will yield in a confluent layer in about 4 days Fluid Renewal: 2 to 3 times per week Post Thaw Recovery: After thawing, plate the cells at 5 x 104 cells/cm2 and allow the cells to recover from the freezing process and to adhere for at least 24 hours. Freeze Medium: 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. Thawing And Culturing Cells: Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks, for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes. Sterility: Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. Safety Precautions: When planning to store a cryovial in liquid nitrogen for future thawing, it is mandatory to adhere to stringent safety measures. Appropriate protective gloves and clothing are essential, and the use of a face mask or safety goggles is required during the transfer of frozen samples to or from the liquid nitrogen tank. This is to mitigate the risk of injury from potential cryovial explosions upon removal, which can result in the projection of sharp fragments.
