Human in vitro generated monocyte-derived dendritic cells (moDCs) and macrophages are used clinically, e.g., to induce immunity against cancer. However, their physiological counterparts, ontogeny, transcriptional regulation, and heterogeneity remains largely unknown, hampering their clinical use. High-dimensional techniques were used to elucidate transcriptional, phenotypic

Microbiological Media and Detection

Molecular biology-based methods, like PCR, can be used for lactobacilli detection. However, they are often quite expensive. We provide a revolutionary molecular biology method that is rapid, easy, and cost-effective.

Probiotics and Human Health

Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue to evaluate the effictiveness and clarify the mechanisms of action of probiotics.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
