Description	The SNU-81 cell line is a human colorectal carcinoma model established from a Korean patient. It is part of a collection of 12 colorectal cancer cell lines derived from both primary tumors and metastatic sites, providing a diverse representation of tumor biology. SNU-81 was derived from a primary colorectal adenocarcinoma and exhibits epithelial morphology with adherent growth in culture. The cell line expresses carcinoembryonic antigen (CEA), which is secreted into the culture supernatant, reflecting typical colorectal tumor characteristics. At the molecular level, SNU-81 has undergone extensive genetic characterization. It harbors a mutation in the TP53 tumor suppressor gene, a common event in colorectal carcinogenesis, typically associated with later stages of tumor progression. Additionally, mutations in the APC gene were identified, implicating disruption of Wnt/β-catenin signaling, a hallmark of colorectal cancer development. No activating mutations were detected in the K-ras2 gene for this line. Alterations in cell cycle regulators, such as hypermethylation of the p16 gene, were also observed, further supporting the cell line's utility in studying genetic and epigenetic mechanisms driving colorectal cancer. Overall, SNU-81 serves as a well-defined in vitro model for exploring tumor suppressor gene function, oncogenic pathway regulation, and response to targeted therapies in colorectal cancer research.

Milieu de culture	RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a)
Suppléments	Supplement the medium with 10% FBS
Réactif de dissociation	Accutase
Temps de doublement	30 hours
Repiquage	Remove medium, add fresh 0.25 % trypsin 0.02 % EDTA solution, stand culture flask at 37''''C for 3 to 5 minutes, add culture medium and collect the cells, transfer the medium into 15ml tube, centrifuge, aspirate the medium, resuspend the pellets with culture medium and dispense into the culture flask
Renouvellement des fluides	2 to 3 times per week
Milieu de congélation	As a cryopreservation medium, we 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.
Décongélation et culture des cellules	Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
Atmosphère d'incubation	37°C, 5% CO₂, humidified atmosphere.
Conditions d'expédition	Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.
Conditions d'entreposage	For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Stérilité	Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.
