Jurkat

Jurkat cells, which originated from the peripheral blood of a 14-year-old with T-cell acute lymphoblastic leukemia (T-ALL), are a well-known human T lymphocyte cell line commonly used in cell biology studies, particularly in cancer research and immune system disorder investigations. These cells play a crucial role in understanding various cellular processes, including cell death mechanisms, autophagy activity, and cytoplasmic transcription factors.

Jurkat cells are commonly used in HIV research due to their expression of the CD4 receptor on their cell membrane. The CD4 receptor is a primary receptor that HIV uses to enter host cells. Because Jurkat cells express this receptor, they can be infected by HIV, making them a useful model for studying HIV's interactions with human T cells, which are a major target of the virus in the human body. The utilization of Jurkat cells in HIV activation and the HIV infection life cycle studies has significantly contributed to understanding the virus's interactions with human cells and has been instrumental in identifying potential targets for antiretroviral therapies.

Jurkat cells further play a pivotal role in biomedical research, particularly in the evaluation of cytotoxicity and cell viability assays. This makes them indispensable for testing the effectiveness of potential cancer therapies and agents that modulate the immune response. By employing Jurkat cells, scientists can meticulously analyze the effects of cytotoxic compounds on the integrity and function of the cell membrane, including aspects related to cell membrane permeability and their transport properties.

Furthermore, the presence of mutations in the Lck gene within Jurkat cells, which leads to sustained activation of T-cells, provides a unique model for in-depth studies of T-cell activation and signaling pathways. This is essential for understanding the complex processes of lymphocyte activation, which encompasses the cell cycle, cellular growth, and differentiation. Such insights are crucial for developing strategies to modulate immune responses in various diseases.

The creation of a specific Jurkat cell derivative, known as Jurkat E6.1, has significantly advanced our comprehension of cellular mechanisms. This derivative offers a refined tool for probing into the nuanced behaviors of cell membranes and the physiological responses of individual cells under experimental conditions. Through the use of Jurkat E6.1 cells, researchers have been able to shed light on fundamental cellular processes and their implications for health and disease.

In summary, Jurkat cells serve as invaluable tools in a wide range of research areas, from cancer biology to HIV infection studies, offering insights into cell biology, immune system function, and potential therapeutic interventions.

37°C, 5% CO₂, humidified atmosphere.

1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

2. 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.

3. 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.

4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

5. 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.

6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

7. 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.

8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.

To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.

For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.

At Cytion, we stand behind the quality and viability of our products. We guarantee that our cells will be viable at the start of culture for 60 days after shipment from our facilities. We assure that all materials conform to the specifications described in the Certificate of Analysis and/or Product Sheet.
