- Receptors expressed: Peptide hormone, neurotransmitter
- Antigen expression: Keratin + (Immunoperoxidase staining)
- Isoenzymes: G6PD, B, PGM1, 1, PGM3, 1, ES-D, 1, Me-2, 1-2, AK-1, 1, GLO-1, 1-2
- Tumorigenic: Yes, in nude mice
- Products: Carcinoembryonic antigen (CEA), 600 ng/ml per 10 exp6 cells per 10 days, keratin
- Mutational profile: T84 cells carry a heterozygous Kras mutation in codon13: GGC(Wt Gly) >GAC(Asp)
- Karyotype: The stemline modal chromosome number is 56, occurring at 28% with polyploidy at 12.4%. Eighteen markers are common to most metaphases examined. Normal x and chromosome 13 were absent, chromosomes 2, 4 and 22 were single-copied, and chromosome 12 was 4-copied.No Y chromosome was detected by Q band observation. DM occurred in nearly 50% of the cells.
- cultureMedium: Ham's F12, w: 1.0 mM stable Glutamine, w: 1.0 mM Sodium pyruvate, w: 1.1 g/L NaHCO3 (Cytion article number 820600a)
- supplements: Supplement the medium with 10% FBS
- dissociationReagent: Accutase
- 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.
- fluidRenewal: 2 times per week
- 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.
