Immortalized Human Tonsillar Epithelial Cells (HTE)

Mfr.No.	T0721
Description	Immortalized Human Tonsillar Epithelial (HTE) cells are isolated from healthy adult patient biopsy and immortalized by being transfected with human papillomavirus type 16 (HPV16). HTE cells can be a useful cell line model as HPV-transfected human tonsillar epithelial cells for studying the HPV pathology and the role of HPV in the etiology of HPV related cancer. HTE cells can also be used as a cell model to study human tonsillar epithelial cell physiology and function.

Quantity	1x106 cells / 1.0 ml
Tissue	Tonsil
Morphology	Other
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.
Organism	Human (H. sapiens)
Population Doubling	48 - 55 hours
Species	Human (H. sapiens)
Propagation	Use Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. Grow cells in ECM-coated culture vessels with the following conditions. The base medium for this cell line is Prigrow III medium available at abm, Cat. No. TM003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (TM999)* to a final concentration of 10% and Penicillin/Streptomycin Solution (G255) to a final concentration of 1%. This cell line needs to be cultured in collagen coated flasks. Carbon dioxide (CO2): 5%, Temperature: 37.0* abm does not recommend to use heat-inactivated FBS for cell culture unless specified otherwise.
Cryopreservation	Cryopreservation Medium (TM024), or complete growth media with 10% DMSO.
Quality Control	Real Time PCR was used to quantify the transgene expression.

Applications Range	Research Use Only.

Shipping	Ship with dry ice.
Product Format	Frozen
Product Use	This product is intended for laboratory research use only. It is not intended for any animal or human therapeutic use, any human or animal consumption, or any diagnostic use.
Storage	Vapor phase of liquid nitrogen, or below -130?.

Thawing Protocol	Feeder cells (NIH 3T3 J2 fibroblasts) must be prepared prior to thawing T0721. To prepare the feeder cell layer:Thaw?IH 3T3 J2 fibroblasts as per supplier instructions.?nce?ibroblasts reach 40-50% confluency, add Mitomycin C (15 ug/mL) and incubate at?7? for three hours.?emove mitomycin C containg growth media and wash cells for a total of 5X using PBS (1X) to remove any residual traces of mitomycin C.?dd fresh growth media to the culture vessel and incubate at?7? (5% CO2) for 1-2 hours to allow cells to adapt.?ote: feeder cells may change morphology post-treatment with mitomycin C and some floating cells may be observed. Although cells may appear bigger in size and present multiple nuclei, confluency should not increase post-treatment.?he feeder lay is now ready for T0721. Prepare T0721 for co-culture:?haw 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. 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. 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.Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media. Co-culture T0721 and?IH 3T3 J2 fibroblasts feeder cells:?spirate feeder cell growth media from the culture vessel containing?IH 3T3 J2 fibroblasts feeder cells and replace with?0721 complete growth media.Add the re-suspended T0721 cells (from step 4 above) to the culture vessel and incubate cells according to the recommended culture conditions.?T0721 may take additional time to recover from post-thaw conditions, therefore, allow cells to attach over the next 24-48 hours before changing media.? successful co-culture will present growing colonies of T0721 between the feeder cells. T0721 cells may grow on-top of one another.
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.Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel. Incubate at?7? for one minute to remove feeder cell layer.?bserve the cells under a microscope to confirm detachment (typically within 2-10 minutes) of only the feeder cells. Collect the suspended feeder cells and discard.Add 2-3ml of fresh, pre-warmed 0.25% Trypsin-EDTA to the culture vessel. Incubate at?7? for 2-3 minutes.?bserve the cells under a microscope to confirm detachment (typically within 2-10 minutes).?eutralize Trypsin-EDTA by adding an equal volume of the complete growth media to the culture vessel.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.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 that have a feeder cell layer ready.?ncubate the cells at the recommended conditions.
