- Antigen expression: Blood Type O, Rh+
- Isoenzymes: Me-2, 2, PGM3, 1-2, PGM1, 1, ES-D, 2, AK-1, 1, GLO-1, 1-2, G6PD, B
- Tumorigenic: Yes, in nude mice and also in hamster cheek
- Karyotype: Hypodiploidy to pseudodiploidy. Abnormalities including double minutes, breaks, large submetacentric, telocentric and small telocentric markers (originator). (P32) Hypodiploid to hyperdiploid and triploid to hypotetraploid with abnormalities including dicentrics, breaks, double minutes (DM), large subtelocentric and small telocentric chromosomes.
- cultureMedium: EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 2.2 g/L NaHCO3, w: EBSS (Cytion article number 820100a)
- supplements: Supplement the medium with 10% FBS and 1% NEAA
- dissociationReagent: Accutase
- doublingTime: 32 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.
- seedingDensity: 1 to 2 x 104 cells/cm2
- fluidRenewal: 2 to 3 times per week
- postThawRecovery: 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.
- freezeMedium: As a cryopreservation medium, use 50% basal medium + 40% FBS + 10% DMSO, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
