Cell Line QC Testing

Cell line authentication has long been recognised as a cornerstone of robust scientific research, yet misidentified and contaminated cell lines continue to undermine the reliability and reproducibility of published studies. Despite increasing awareness and the introduction of authentication guidelines, the question remains: how widespread is the problem in laboratories today? Our perspective on cell line authentication In our recent Frontiers

Your cell lines are the foundation of your project. Whether you’re conducting biomedical research, drug discovery or therapeutic development, the reliability of your work depends on the quality and integrity of your cell lines. However, cell line contamination and misidentification remain among the most common challenges faced by laboratories worldwide. In fact, 33% of cell lines are misidentified or contaminated

In research and development, your cell lines are among your most valuable assets. Yet the journey from qualification to long-term storage is often fragmented. Samples are frequently transferred between laboratories for testing and off-site storage facilities, introducing unnecessary risk at a critical stage of the research lifecycle. Safeguarding your assets shouldn’t be a logistical challenge. That’s why, at Biofortuna, we

It’s a question you may not have considered, but a growing number of outsourced cell line QC providers are sending samples overseas. At a time when global logistics are increasingly complex and sustainability is becoming an increasingly important consideration, this “standard” process is generating unnecessary carbon emissions and sending critical biological material abroad is increasingly difficult to justify. Beyond the

The identity and purity of your cell lines are essential to the integrity of your research. Misidentified or contaminated cell lines lead to irreproducible data and costly errors, and without regular cell line authentication you risk wasting time and resources, potentially invalidating years of work. Regular cell line authentication through STR profiling offers a clear solution to verify cell line

The cell line is the starting point for any application that relies on biology, including diagnostic manufacturing, academic discovery and biopharmaceutical development. Whether you’re conducting fundamental research, producing vaccines or diagnostic reagents, the quality and reliability of your cell line directly determines the efficacy, reproducibility and trustworthiness of your results or product. That’s why cell line characterisation is a critical,

Cell lines provide the foundation for scientific discovery. From the development of life-saving therapies to technological advancements, their quality directly dictates the reliability of findings, ensuring they lead to valid discoveries. However, without rigorous cell line quality control (QC), you risk compromising everything from data integrity to product safety, potentially wasting valuable time and resources. Cell line QC isn’t just

Sterility testing is a quality control process used to ensure that a cell line is free from microbial contamination. This is crucial when working with cell cultures in research, diagnostics, biomanufacturing, and clinical applications. What does Sterility testing do? Sterility testing typically screens for bacteria (aerobic and anaerobic), mycoplasma and fungi and yeast How is it done? Cell culture materialRead more

Mycoplasma is a unique genus of bacteria. Unlike most bacterial species, Mycoplasma lacks a cell wall allowing it to assume diverse shapes. These characteristics challenge the effectiveness of antibiotics in cell culture media, as many antibiotics target the bacterial cell wall. Mycoplasma, among the tiniest bacteria (0.2–0.8 µm in size), presents a stealthy contamination risk. How can Mycoplasma contamination impactRead more

It is estimated that 33% of cell lines used in research are misidentified or contaminated. Therefore, routine testing is fundamental. Cell line authentication is a crucial step in scientific research, especially in fields such as cell biology, genetics, and biomedical research. According to current research and best practice guidelines, cell line testing is recommended: Before submitting a paper for reviewRead more
