  • Best practices in proteins sample preparation with Precellys® evolution

    Proteins are the building blocks of life. They are vital to our existence and are found in every organism on Earth. As antibodies, enzymes or even hormones, proteins are implicated in chemical reactions, immunological processes and cell activities. Proteins also play a role in movement, structural support, storage, communication between cells, digestion and substances transportation. There is a ...

  • Best practices for sample preparation & lipid extraction from various sample

    Lipids play a structural role in organisms, forming cells and organelles’ membranes. Not only do they store energy, but recent studies also showed their role as first and second messengers in signal transduction. As they are implicated in widespread pathologies such as cancer or inflammation, they have become a major concern for the scientific community.Here, we present three case studies ...

  • Best practices for tough sample grinding in molecular biology using Precellys®

    The biggest challenge when working with fibrous, elastic and tough samples is efficient sample processing. The presence of elastic tissue, calcium phosphate (a rock-hard mineral) and other minerals can develop into a solid and tough matrix which can sometimes be difficult to homogenize. Moreover, heat generation inside the lysing kit tubes during the process results in degradation and ...

  • Best practices in marine sample preparation with the Precellys® range

    Green house gas emissions might lead to a "collapse" of marine species and thus of the food chain. 10 to 12% of the species might disappear if the temperature increases by 2°C compared to thepre-industrialera. Advances in  research regarding the behavior of the marine world using protein markers, genetics and direct observations allow researchers to better apprehend the biodiversity and ...

  • Are you recycling polystyrene the right way? Don’t risk the heavy fines

    While there’s a European-wide drive to recycle more polystyrene, some forms of it contain a flame retardant that is hazardous to human health and the environment. The idea of the circular economy is a compelling one, and it’s driving recycling policies worldwide across industries. There is more focus than ever is on the complete lifecycle of products, including packaging, vehicles and ...

  • Sample preparation is the key to quality analysis with a laser analyser

    Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

  • Some notes about Fats and Oils in Food and about FAME and FAMEWAX

    In Europe, the last transition periods named in REGULATION (EU) No 1169/2011 on the provision of food information to consumers are running out on Dec. 13th, 2016. Since then, a nutrition declaration is mandatory for nearly all packed food in Europe, wherein the amounts of fat, saturates, carbohydrate, sugars, protein and salt have to be included. The content of the mandatory nutrition ...

  • Solvent-Free Synthesis of c-Axis Oriented ZSM-5 Crystals with Enhanced Methanol to Gasoline Catalytic Activity

    ZSM-5 crystals with controllable c-axis length were successfully synthesized through a one-pot solvent-free route, with urea as an additive. X-ray diffraction patterns (XRD) show that the prepared samples exhibit high crystallinity. N2 adsorption–desorption isotherms and mercury intrusion porosimetry (MIP) analysis together with TEM observations indicate that micro-, meso-, and ...

  • Metabolic Blurred Lines: Is Biotransformation the next Met ID?

    You are the hunter in a landscape of scientific gatherers, the stealthy SEAL of DMPK, the nimble ninja of ADME. You are a Metabolite ID scientist. Traditionally, Met ID labs have been a fixture of any pharmaceutical company worth its salt. Now, imagine that your proud band of comrades has been phased out, split up, and distributed throughout your organization. Chances are, you don’t need to ...

  • 3 Reasons for Biopharmaceutical Labs to add Mass Detection to Routine Analyses

    As regulators focus in on the critical quality attributes (CQAs) of biotherapeutics, what can biopharmaceutical labs in late development or QC do to increase confidence in their bioseparations assays – other than to run additional orthogonal assays? Many labs are finding the answer in mass detection, specifically with the ACQUITY ...

  • When Consumables Kits are Greater Than the Sum of their Parts

    ProteinWorks and GlycoWorks kits address more than sample prep challenges One of the most challenging parts of an LC-MS workflow happens before analytical chemists even turn to their instrument: Sample preparation. Get it right, and the analytical run performs as expected. Get it wrong, and the assay has any number of problems, from poor sensitivity to poor reproducibility. The ...
