A Strategic Evolution from CLS to Cytion

Cell biology research is always changing, and so are the organizations that support this important work. We're excited to announce a big change: the transition from CLS (Cell Line Services) to Cytion. This change is more than just a new name—it's about our goal to make premium cell lines available to more researchers worldwide while keeping high quality standards.

For many years, CLS has been trusted by research labs, universities, and biotech companies to provide authenticated cell lines. As Cytion, we're building on this history while finding new ways to better serve scientists globally. Our mission stays the same: to provide researchers with reliable, high-quality cell lines that help make important discoveries to improve human health.

This change comes at an important time in biomedical research, as more researchers need authenticated cell lines for work in immunology, cancer research, virus studies, and drug development. With our new Cytion name, we're improving our ability to meet these needs through better shipping methods, easier product discovery, and simpler ordering processes—all while maintaining the strict quality controls essential for good research.

Our Jurkat cells collection remains one of our most important offerings, providing researchers with reliable T-cell models that have been used in thousands of important studies worldwide.

What This Means for Researchers: No Compromises, Just More

The change from CLS to Cytion brings many benefits for researchers around the world, without sacrificing the quality and reliability that have made our cell lines trusted by scientists. We know that consistency is extremely important in scientific research, which is why we've kept our strict quality control procedures, reliable batch processing methods, and commitment to scientific accuracy throughout this transition. This dedication to maintaining standards while expanding services ensures that laboratories can continue their work without disruption, knowing that the cell lines they receive today will perform just as reliably as those they've used before.

Maintained Quality Standards

Our dedication to providing authenticated cell lines remains as strong as ever. Every cell line in our catalog, including our popular Jurkat cells, continues to undergo thorough testing:

All our cell lines are regularly tested to make sure they are mycoplasma-free, preventing this common contaminant from ruining research results. This testing uses multiple detection methods including PCR-based assays and direct culture techniques to ensure no false negatives occur. Human cell lines undergo Short Tandem Repeat (STR) profiling to verify their identity and detect any cross-contamination, with profiles compared against international reference databases for absolute confirmation. Each batch is checked for consistent growth patterns, cell shape, and behavior through multiple passages to ensure stability. We also have strict standards for cell viability to ensure researchers receive healthy, robust cultures, with minimum viability thresholds that exceed industry standards.

Enhanced Global Services

While maintaining these quality standards, we've also made several improvements to better serve our customers around the world:

We've improved our shipping processes with better temperature control during transit, using specialized containers with advanced phase-change materials that maintain optimal temperatures for up to 72 hours, protecting cell viability even during unexpected delays. Our online ordering system is now more user-friendly with comprehensive product information, including detailed growth characteristics, recommended culture conditions, and application-specific guidance for each cell line. We've increased the availability of scientific experts to help with questions and troubleshooting, with expanded support hours across multiple time zones to accommodate researchers worldwide. And we've enhanced access to certificates of analysis, safety data sheets, and authentication reports, making these crucial documents available for immediate download through our secure customer portal.

Spotlight on Jurkat Cells: Trusted Tools for T-cell Research

Among our wide range of premium cell lines, Jurkat cells stand out as one of our most important offerings for immunology and cancer research. These immortalized human T lymphocytes have become essential tools in laboratories worldwide, contributing to countless breakthrough discoveries in T-cell biology, cell signaling, and immunotherapy development. Their reliability, well-characterized properties, and versatility make them indispensable for researchers investigating immune system function, cancer biology, and drug development targeting T-cell pathways.

The Origin and Significance of Jurkat Cells

Jurkat cells were originally taken from the blood of a 14-year-old boy with T-cell acute lymphoblastic leukemia (T-ALL) in the 1970s. Since then, these cells have become one of the most widely used models for studying T-cell receptor signaling, cell death pathways, and cytokine production. They're so valuable because they behave like normal T-cells in many ways but can be grown continuously in the lab, making them perfect for long-term studies. The establishment of this cell line represented a significant breakthrough in immunology research, as it provided a stable, reproducible system for investigating T-cell functions that would otherwise require constant isolation of primary cells from donors, with all the variability that entails.

Key Applications of Jurkat Cells

T-cell receptor signaling studies

Cytokine production and regulation research

Apoptosis and cell death investigations

Drug screening and development

Gene expression and regulation studies

Cytion's Commitment to Jurkat Cell Quality

At Cytion, we understand how important cell line authenticity and consistency are in research. Our Jurkat cells go through strict quality control measures to ensure they meet the highest standards:

Each batch is verified using STR profiling to confirm the cells' identity and detect any potential cross-contamination, with a comprehensive 16-marker analysis that provides definitive authentication against reference standards. We regularly test to ensure all cultures are free from mycoplasma, bacteria, and other contaminants, employing both PCR-based detection and direct culture methods to catch even low-level contamination that might affect experimental results. The cells are assessed for key characteristics including growth rate, shape, and response to stimuli, with particular attention to their IL-2 production capacity following appropriate stimulation—a critical functional characteristic of this cell line. And we have strict protocols to ensure minimal variation between batches, enabling reproducible research results, including standardized culture conditions, passage numbers, and harvesting procedures that maintain consistent cellular phenotypes.

For neuroinflammation studies, our BV2 cells provide a reliable microglial cell model, another example of our diverse cell line offerings.
