  • Luminous bacterial proteins detect chemicals in water

    While residual medications don’t belong in the water, trace metals from industrial process waters handled by the recycling industry are, in contrast, valuable resources. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a simple color sensor principle which facilitates the more

  • Decomposition of textile products in the ground

    Like all organic materials, textiles will decompose under the influence of water and microorganisms in the ground. Under comparable environmental conditions, it depends mainly on the raw materials used whether the decomposition process takes place over the course of months, years, decades or even ce more

  • Cost-effective Determination of Inorganic Anions and Cations in Municipal Drinking Water

    Thermo Fisher Scientific Inc. announced a new application demonstrating the separation of common inorganic anions and cations in municipal drinking water samples on the capillary Thermo Scientific Dionex IonPac AS19 hydroxide-selective anion-exchange column and the Thermo Scientific Dionex IonPac CS more

  • Real-Time PCR Quantification of Plant miRNAs Using Universal ProbeLibrary Technology

    MicroRNAs (miRNAs) are naturally occurring, highly conserved families of transcripts (18-25 nt in length) that are processed from larger hairpin precursors. Both plant and animal genomes encode miRNAs, and to date, there are over 4000 mature miRNA transcripts annotated. Although miRNAs represent a relatively abundant class of transcripts, their expression levels vary greatly among species and tissues. Less abundant miRNAs routinely fail detection using technologies such as cloning, northern hybridization and microarray analysis. Here, we present a real-time quantification method for accurate, sensitive, and economical detection of plant miRNAs based upon the stem-loop RT primer approach using an miRNA-specific primer coupled with a stem-loop specific Universal ProbeLibrary (UPL) probe. This approach represents a highly specific, sensitive, and easy-to-apply system to detect miRNAs. more

  • Quantitative Detection of Legionella pneumophila in Water Samples: Assay Transfer to the LightCycler® 480 Real-Time PCR System

    An assay to detect and quantify Legionella spp. in water samples was successfully transferred from a capillary-based LightCycler® Instrument to the novel multiwell plate-based LightCycler® 480 System. A previously described protocol was easily adapted by modifying the fluorescent label of the detection probe to match the filter set of the LightCycler® 480 Instrument. While reproducibility and analytical sensitivity of the assay were found to be comparable on both systems, the novel plate-based instrument allowed for higher sample throughput and reduced assay time per sample. more

  • Accurate Mass and TIPTM: Two Dimensions for Elemental Composition Determination: microTOFTM Featuring Unique TIPTM

    The ESI-TOF mass spectrometers micrOTOF and micrOTOF focus do not only provide accurate mass measurements but additionally describe the True Isotopic Pattern TIPTM. For molecular formula generation this unique combination significantly reduces the number of possible formula candidates and the elemental composition of compounds with molecular weights far higher than 500 Da can unequivocally be determined more
