Atmospheric boundary level (ABL) is the lowest part of the atmosphere that is highly influenced by its contact with the surface of the planet. The diverse microorganisms found in the ABL are continuously aerosolized and dispersed from surface sources. Knowledge of microbial diversity in the ABL is crucial as it can be potentially dangerous for […]

Over the past two decades, there has been a substantial increase in the usage of latex products, accompanied by a growing incidence of latex allergies, particularly in healthcare settings. Allergic reactions to latex can range from mild to severe, and even be fatal in some cases. Latex allergy symptoms include skin irritation, runny nose, rash, […]

Steroid hormones such as estrogen can influence the endocannabinoid system (ECS) in the female reproductive tract by increasing the expression of cannabinoid receptors CB1 and CB2 and altering the levels of anandamide (AEA). Tamoxifen, a selective estrogen receptor modulator, can affect AEA regulation in the central nervous system. AEA levels in the hypothalamus and pituitary […]

Atopic dermatitis (AD) is an inflammatory skin disease causing itching and redness. CGRP (calcitonin gene-related peptide) is a neuropeptide that plays an important role in pain and inflammation. Recent studies have suggested that CGRP may be involved in the pathogenesis of atopic dermatitis. Indeed, an increase in CGRP expression has been observed in skin with […]

Preparing high-quality emulsions is a critical step to successfully generate specific antibodies. The generation of antigen-specific antibodies is especially important since it involves the injection of an immunogenic antigen-adjuvant emulsion in animals at defined time intervals. The two-syringe technique is widely employed as the standard method for emulsion preparation. Despite its popularity, this method has […]

Gluten is a protein contained in certain cereal grains. Despite its ubiquity, some people can develop severe gluten allergies. Recently, the number of customers interested in gluten-free products has increased. To keep up with the demand, the food industry has to exclude gluten from their offer and come up with new “safer” products. The air […]

Nucleic acid isolation is an essential step in molecular biology and is the starting point of most downstream experiments. As these molecules are fragile, it is important to ensure efficient grinding while preserving biological compounds. Precellys homogenizers have been used for DNA and RNA extraction and sample preparation all over the world for many years. […]

Bertin Bioreagent offers two kits to extract DNA and total RNA from animal tissues. These kits are part of a complete sample preparation workflow that starts with tissue homogenization using Precellys instruments and whose quality has been validated by Bertin Health & Life Sciences R&D team. DNA extraction is a critical step in molecular biology […]

In April 2021, air sampling was conducted in outdoor restaurant terraces in three major cities in Portugal to collect data on the presence of SARS-CoV-2. Nineteen air samples were collected during lunchtime using Bertin’ Coriolis Compact air sampler, and one of the samples tested positive for SARS-CoV-2 RNA. This low number of positive samples was […]

Intravenous immunoglobulin (IVIG) is known for its anti-inflammatory effects and is commonly used to treat auto-immune and systemic inflammatory diseases. Basophils are a type of white blood cells that are responsible for inflammatory reactions during the immune response and produce inflammatory mediators such as histamine and serotonin. Recently, it has been reported that, the anti-inflammatory […]
