Capan-1 Cells

The Capan-1 cell line is derived from a human pancreatic adenocarcinoma and was established from the ascitic fluid of a 40-year-old Caucasian male. It was first characterized in 1975 and is particularly noted for its ductal epithelial morphology, which closely resembles that of primary pancreatic tumors. Capan-1 cells are extensively used in research aimed at understanding pancreatic cancer biology, including studies on tumor progression, metastasis, and treatment resistance. This cell line is well-regarded for its ability to produce mucin, a characteristic feature of many pancreatic adenocarcinomas, thus serving as a model for mucinous pancreatic cancer.

Genetically, Capan-1 harbors mutations in the KRAS gene, which are typical of pancreatic cancer, as well as alterations in other cancer-related genes such as TP53 and SMAD4. These mutations make the Capan-1 cell line a valuable tool for studying the molecular mechanisms underlying pancreatic cancer and for the preclinical evaluation of new therapeutic agents targeting these pathways. Furthermore, Capan-1 cells are used to study the biology of pancreatic cancer stem cells, offering insights into the behaviors that drive cancer recurrence and resistance to conventional therapies.

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.

After thawing, plate the cells at 5 x 10^4 cells/cm^2 and allow the cells to recover from the freezing process and to adhere for at least 48 hours.

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.

When planning to store a cryovial in liquid nitrogen for future thawing, it is mandatory to adhere to stringent safety measures. Appropriate protective gloves and clothing are essential, and the use of a face mask or safety goggles is required during the transfer of frozen samples to or from the liquid nitrogen tank. This is to mitigate the risk of injury from potential cryovial explosions upon removal, which can result in the projection of sharp fragments.
