How to Keep Fragile Jurkat Cells Alive During Transfection — A Practical Survival Guide
Jurkat (Clone E6-1) cells are a classic model for T cell research. They have been established in the 1970s and have been widely used in immune mechanisms, disease research and drug development.

Basic characteristics of Jurkat cells
Basic characteristics
The Jurkat Clone E6-1 cell line was born in the 1970s and was derived from the peripheral blood of a 14-year-old patient with acute T lymphoblastic leukemia (T-ALL). As an immortal human T lymphocyte line, it has the following unique advantages:
- Suspension growth characteristics
- Synergistic stimulation by Phorboate/exogenous lectin or anti-CD3 monoclonal antibody can efficiently secrete IL-2
- Expressing a variety of chemokine receptors (CXCR4, etc.), highly susceptible to viruses such as HIV

The core application of Jurkat cells in biomedical research
Core applications
Jurkat cells are widely used and are mainly used to study issues related to immunology and cancer biology.
1. Basic immunology research
- TCR signaling pathway analysis: tyrosine kinase activation, calcium ion flow and NF-kB activation
- Cytokine regulatory network: IL-2, IFN-γ and other production and secretion mechanisms
- Research on the formation and function of immune synapses
2. Tumor biology research
- Pathogenesis of acute T-cell leukemia
- Regulation of leukemia cell proliferation and apoptosis
- Identification of targets of action of anti-T-ALL drugs
3. Virology application

- Antiviral drug screening platform
- Research on T-cell viruses such as EBV/HPV
4. Molecular mechanism research
- Non-coding RNA functions (such as M1-RNA)
- MHC Class II molecular expression regulation (CTATA pathway)
- Epigenetic modification research
5. Translational medicine applications
- Research and development of CAR-T cell therapy
- Evaluation of immune checkpoint inhibitors
- Development of new immunomodulatory agents
6. Genetic engineering technology

Difficulties and efficiency improvement of Jurkat cell transfection
Difficulties in transfection
1. The main difficulties of Jurkat cell transfection
1. Suspension growth characteristics
Compared with adherent cells, the contact efficiency between suspended cells and transfection reagents is low.
2. Poor cell membrane stability
Electroporation or chemical transfection can easily cause membrane rupture and high cell mortality.
3. Low cracking activity
Division is slow (compared to cells such as HEK293), which limits the efficiency of genome integration of viruses or plasmids.
4. High endogenous nuclease activity
Exogenous DNA/RNA is easily degraded.
2. General techniques to improve the efficiency of Jurkat cell transfection
