The microbiome is at the heart of numerous research fields, from human health to environmental sciences. Whether characterising complex microbial communities, studying the impact of microorganisms on their environment, or monitoring bioaerosols, the quality of the results depends directly on the quality of the samples analysed.

What if viruses could travel around the world… simply carried by the wind? Invisible to the naked eye, this phenomenon is very real. Viruses circulate through the atmosphere, traveling thousands of kilometers, crossing oceans and continents to reach some of the most remote regions on Earth, such as sub-Antarctic South Georgia. A reality that challenges our understanding of ecosystems and highlights just how interconnected they are on a global scale.

In lipidomics studies, data quality depends first and foremost on sample integrity. Yet lipids are among the biomolecules most susceptible to oxidation. From the moment of collection, natural reactions can alter their composition, creating discrepancies between the sample’s true biological state and the data ultimately obtained during analysis. This early degradation is mainly driven by free radicals present in the blood. Even before sample preparation or storage, these highly reactive molecules can affect certain lipid species and generate artifacts that may influence quantification and data interpretation. For laboratories working in metabolism, inflammation, cardiovascular research, or neuroscience, controlling this phenomenon is a critical challenge.

Pathogens represent a constant threat to aquaculture operations and can significantly impact fish health, production performance, and farm profitability. In Recirculating Aquaculture Systems (RAS), where water is continuously reused to optimize resources and farming conditions, early virus detection is essential to protect stock health, limit the risk of pathogen spread, and strengthen facility biosecurity.

Prion disease research is no longer limited to traditional models such as mice and hamsters. Today, studies and surveillance programmes for transmissible spongiform encephalopathies (TSEs) also involve cattle, small ruminants, cervids and camelids.
This diversification raises an important question: will your antibody still recognise its target when you switch animal models?The anti-PrP monoclonal antibodies SAF32 (A03202) and Sha31 (A03213) provide a practical answer. In the published studies reviewed, these two clones have been used to detect the PrP protein in 10 species belonging to 5 mammalian orders, ranging from primates to marsupials (1-12).

Just like notebooks and pens belong on every school supply list, some lysing kits are simply essential in the laboratory. Every sample is unique, and choosing the right lysing kit is key to achieving efficient homogenization and reliable results. Whether you’re working on DNA, RNA, protein, or metabolite extraction, Precellys® offers a comprehensive range of […]

Sample preparation is a critical step in molecular biology, especially when working with fibrous, elastic, or mineralized samples. These complex matrices can be difficult to homogenize and may put extraction workflows to the test. 

Maximizing protein extraction efficiency is a critical step in biological research. A comparative study evaluated the Precellys Evolution Touch, featuring advanced 3D bead-beating technology, against conventional sonication. Tested on fresh frozen pig liver biopsies, the study demonstrated that Precellys Evolution Touch delivers higher protein yields, faster sample processing, and improved reproducibility, significantly outperforming sonication.

Airborne microorganisms represent a major challenge for healthcare facilities. Controlling environmental contamination is essential to reduce the risk of healthcare-associated infections and ensure the safety of both patients and healthcare professionals. In this context, evaluating the effectiveness of air purification systems has become a key component of infection prevention strategies.

Bacteriophages, or phages, are viruses that infect bacteria. In the dairy industry, they represent a major challenge as they can attack the lactic cultures essential for the production of products such as cheese, yogurt, and fermented milk. Often undetected until the first signs of process failure appear, they can disrupt fermentation processes and affect the quality of finished products. The consequences of contamination can be significant.
