Enhanced Primary Human Hepatocytes are expanded primary cells which retains the physiologically relevant profile and phenotype of primary hepatocytes. These cells are ready-to-use for applications in research and development, such as viral infections, screening, co-cultures, transient transfection, and for metabolism studies. The late expansion cells are tested for CYP induction and inhibition. It is not recommended for further extensive passaging after thawing but can be used for long term culture which is necessary for cell-based assays.
To make complete Hepatocyte Growth Basal Medium add the entire content of Hepatocyte Growth Supplement Mix into Hepatocyte Growth Basal Medium and mix properly in BioSafety Cabinet. Addition of the Hepatocyte Growth Supplement Mix may change medium appearance more opaque.
To thaw:
1. Pre-warm Hepatocyte Thawing Medium and fully supplemented Hepatocyte Growth Medium to room temperature.
2. Carefully remove cryovial from storage tank.
3. Thaw cells in 37? water bath until only a small chunk of ice is left.?o not shake the vial, or take it out of the water during thawing, as this will damage the cells.
4. Spray the vial and the tube containing 50 ml of thawing medium with 70% ethanol and transfer to a Biosafety cabinet.
5. Transfer the now completely thawed cell suspension from the cryovial into 50 ml Hepatocyte Thawing Medium by gently pouring the cells into the medium.
6. Use a 1 ml pipette to transfer 1 ml of the thawing medium back to the cryovial and pour the contents back into the 50 ml tube. Repeat this process twice to completely remove the cells from the cryovial.
7. Pellet the cells by centrifuging at 90? for 5 min at RT. Important note:?igher g-forces will significantly reduce cell recovery.
8. Aspirate the supernatant without disturbing the pellet. Leave approximately 200-400 ?l medium on top of the cells. 9. Gently loosen and re-suspend the cells without adding any extra medium by agitating and rotating the tube.?o not vortex or shake the cells as this will compromise cell survival.
10. Add an appropriate volume of pre-warmed supplemented Hepatocyte Growth Medium to the pellet (~1ml per million cells thawed) and re-suspend the cells.?void pipetting the cells up and down.
11. Determine viable cell number by cell count.

Notes
1. Visually examine the packaging containers for signs of leakage or breakage. 2. Immediately transfer frozen cells from dry ice packaging to a temperature below -130?, preferably in liquid nitrogen vapor phase storage, until ready for use.To ensure the highest level of viability, thaw the vial and initiate culture as soon as possible upon receipt. If continued storage is desired, the vial should only be stored below -130? or in liquid nitrogen vapor phase. Do not store at -70?, as it will result in loss of viability.

Thawing Protocol
1. Thaw cells quickly in a 37? water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination. 2. Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions. 3. Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 125xg for 5-7 minutes. 4. Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask. 5. Incubate the cells at the recommended conditions.
Subculture Protocol
Volumes given below are for a T75 flask; proportionally increase or decrease the volume as required per culture vessel size. Subculture cells once the culture vessel is 80% confluent. 1. Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel. 2. Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37?, for several minutes to facilitate detachment. 3. Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel. 4. Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type. 5. Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired. 6. Incubate the cells at the recommended conditions.
