Wild-type cell lines are sold with knockout cell lines only - not available for individual purchase.

Cryopreservation cell medium: Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Culture medium: 1:1 mixture of EMEM and F-12K + 10% FBS

Initial handling guidelines: Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80ºC. Storage at -80ºC may result in loss of viability.

1. Thaw the vial in 37ºC water bath approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 ml) to a 15 ml/50 ml conical sterile polypropylene centrifuge tube containing 8.4 ml pre-warmed culture medium, wash vial with an additional 0.8 ml culture medium (total volume 10 ml) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 ml represents minimum recommended dilution. 20 ml represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 ml pre-warmed culture medium and count using a haemocytometer (Click here to view haemocytometer protocol) or alternative cell counting method. Based on cell count, seed cells in an appropriate cell culture flask at a density of 2x10⁴ cells/cm². This should allow for confluency within 48 hours. Seeding density is given as a guide only and should be scaled to align with individual lab schedules.
4. Incubate the culture at 37ºC incubator with 5% CO₂. Cultures should be monitored daily.

Subculture guidelines:

• All seeding densities should be based on cell counts gained by established methods.
• A guide seeding density of 2x10⁴ cells/cm² is recommended for confluency (80-90% confluence) within 48 hours.
• A partial media change 24 hours prior to subculture may be helpful to encourage growth, if required.
• Cells should be passaged when they have achieved 80-90% confluence.
