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. 3. This cell line has a finite lifespan. Excessively high passage numbers will alter cellular growth characteristics. Laboratory verification confirms a maximum of 4–5 achievable passages. All experiments are recommended to be completed within 3 passages after cell delivery.
Complete Medium	MEM, with NEAA [PM150410]+10% Nutrient+1% Supplement
Incubation Atmosphere	Air, 95%; CO₂, 5%
Temperature	37℃
Subcultivation Ratio	1:2
Medium Renewal	2 to 3 times per week
Dissociation Duration	1-2 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	General Freezing Medium [PB180436]
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.

Reference materials

Background	The WI-38 cell line was derived from normal embryonic lung tissue obtained from a 3-month-gestation fetus. As the first human diploid cell line used for human vaccine preparation, WI-38 cells can be promoted to grow by adding TNF-α to the culture medium.
Biosafety Level	BSL-1
