- Antigen expression: blood type O, Rh+
- Isoenzymes: G6PD, B, PGM1, 1-2, PGM3, 1-2, 6PGD, A, PEP-D, 1, ES-D, 1
- Oncogenes: The line is positive for expression of c-myc, K-ras, H-ras, N-ras, myb and fos oncogenes. N-myc and sis expression were not detected.
- Tumorigenic: Yes, in nude mice
- Reverse transcriptase: Negative
- Products: Carcinoembryonic antigen (CEA) 7 ng/106 cells/10 days, colon specific antigen (CSAp) 750 units in 0.5 ml cell sonicate, keratin
- Mutational profile: SW-948 cells carry a heterozygous Kras mutation in codon 61: CAA(Wt Gln) >CTA(Leu)
- 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
- 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 x 104 cells/cm2
- fluidRenewal: 1 to 2 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 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.
