Handling information

Instructions	1. Check all containers for leakage or breakage. 2. Remove the frozen cells from the dry ice packaging and immediately transfer them to liquid nitrogen (liquid or vapor phase) for long-term cryopreservation.
Complete Medium	DMEM [PM150210]+10% Nutrient+1% Supplement
Incubation Atmosphere	Air, 95%; CO₂, 5%
Temperature	37℃
Subcultivation Ratio	1:3-1:5
Medium Renewal	2 to 3 times per week
Dissociation Duration	2-3 min
Subculturing Procedure	1. Remove the culture medium from the T25 cell culture flask. 2. Add approximately 2 mL of PBS. Gently tilt the flask side to side until the PBS covers the entire bottom, then aspirate and discard the PBS. 3. Add 1 mL of 0.25% trypsin solution (containing EDTA). Gently tilt the flask side to side until the trypsin solution covers the entire bottom of the flask. 4. Incubate the cells at 37°C. Observe the cells under an inverted microscope and terminate digestion once the cells round up and detach. To avoid clumping, do not agitate the cells by tapping or shaking the flask during detachment. 5. Add 3 mL of complete culture medium to terminate digestion and disperse into a single cell suspension. 6. Collect the cell suspension and centrifuge at 1200 rpm (approximately 250 ×g) for 3 minutes. Carefully aspirate and discard the supernatant. 7. Add fresh complete culture medium, pipette gently several times to resuspend the cells, and seed them at the appropriate ratio into a new culture flask. Loosen the cap or use a vented cap for incubation.
Freeze Medium	Freezing Medium (Serum-free & animal origin-free) [PB180438]
Storage Conditions	For long-term cryopreservation, cryovials should be stored in liquid nitrogen at −150°C to −196°C. Storage at −80°C is restricted to short-term interim use only.

Background

GES-1 cells were isolated and cultured from gastric epithelial cells of a 9-month-old human fetus, and established following SV40 virus transfection and selection. Apart from their transformed characteristics, GES-1 cells largely retain normal cytoskeletal structures, including microfilaments, microtubules, and keratin, and are positive for mucin staining. GES-1 cells exhibit no tumorigenicity in nude mice after 6 months of observation, confirming their non-tumorigenic nature. This cell line serves as an important model for investigating human gastric carcinogenesis and is widely used in gastric cancer research, drug screening, toxicology studies, and related fields.
