Growth Properties
Suspension
Morphology
Epithelial-like
Propagation
Complete growth medium: Serum-free Medium
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37°C
Starting Cells From Frozen Cell Stock
1. Remove the packaging cell lines from liquid nitrogen and carry out a quick thaw. Float the cells in the 37°C water bath for 2 minutes until nearly (80%) thawed.
Once cells are thawed, it is important to dilute the cells 1:10 in growth media immediately to reduce the potentially toxic effects of the DMSO preservative on the cells.
2. Clean the outside of the vial with 70% ethanol before opening.
3. Remove the cells from the vial and add slowly into a 15ml conical tube containing 10 ml pre-warmed media.
4. Centrifuge for 3 minutes 1000 xg to pellet cells and remove the supernatant.
5. Add 14 ml of media and transfer cells to a T25 flask or a 100 mm culture dish.
6. Place the cells in the 37°C incubator with 5% CO2.
7. Allow incubation for 3-4 days to reach confluence. The cells will re-attach to the surface over a period of several days in culture at 37°C.
Subculturing
1. Centrifuge for 5 minutes 300 xg and discard culture medium.
2. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
3. Add appropriate aliquots of the cell suspension to new culture vessels.
Incubate cultures at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended
Medium Renewal: 2 to 3 times per week
Mycoplasma
Mycoplasma Status: Negative (MycoAlert Kit)
Freeze Medium
Complete growth medium 90%; DMSO, 10%
Safety Considerations
The following safety precautions should be observed.
1. Use pipette aids to prevent ingestion and keep aerosols down to a minimum.
2. No eating, drinking or smoking while handling the stable line.
3. Wash hands after handling the stable line and before leaving the lab.
4. Decontaminate work surface with disinfectant or 70% ethanol before and after working with stable cells.
5. All waste should be considered hazardous.
6. Dispose of all liquid waste after each experiment and treat with bleach.

Background
Antigen Description
IgE is typically the least abundant isotype - blood serum IgE levels in a normal ("non-atopic") individual are ~150 ng/ml, compared to 10 mg/ml for the IgGs - it is capable of triggering the most powerful immune reactions. Most of our knowledge of IgE has come from research into the mechanism of a form of allergy known as type 1 hypersensitivity. There is much speculation into what physiological benefits IgE contributes, and so far, circumstantial evidence in animal models and statistical population trends have hinted that IgE may be beneficial in fighting gut parasites such as Schistosoma mansoni, but this has not been conclusively proven in humans. IgE may play an important role in the immune system"s recognition of cancer, in which the stimulation of a strong cytotoxic response against cells displaying only small amounts of early cancer markers would be beneficial. IgE may be an important target in treatments for allergy and asthma.
