  • The Swedish initiative to map all human proteins reaches half-way point

    Scientists in Sweden marked the half way point of a major, ground-breaking initiative to map every single protein in the human body. Once complete, the Human Protein Atlas will provide scientists with data which will help detect and treat some of the world’s most serious health problems such as canc more

  • NYU Langone scientists are first to sequence the genomes of 2 ant species

    Scientists have finally sequenced the entire genome of an ant, actually two very different species of ant, and the insights gleaned from their genetic blueprints are already yielding tantalizing clues to the extraordinary social behavior of ants. A result of a collaborative research project led by D more

  • The Porcine microRNAome is revealed

    Researchers from LC Sciences LLC and a collaboration of universities have established a porcine microRNAome, a complete catalog of all microRNAs expressed in the species Sus scrofa. MicroRNAs (miRNAs) are small regulatory RNA molecules known to control a wide array of cellular functions such as gr 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

  • MagNA Pure Compact RNA Isolation Kit: Isolation of High-Quality Total RNA from a Broad Range of Sample Material

    The MagNA Pure Compact Instrument together with the new MagNA Pure Compact RNA Isolation Kit can be used for automated isolation of total RNA from blood, blood cells, tissue, and cultured cells. The MagNA Pure Compact System perfectly fits into Roche Applied Science's integrated solution for real-time PCR: The MagNA Lyser Instrument, Universal ProbeLibrary, Transcriptor First Strand cDNA Synthesis Kit and FastStart TaqMan® Probe Master. more

  • Fugene® HD Transfection Reagent: Superior Performance for Challenging Expression Studies

    The ability to efficiently introduce foreign molecules into cells constitutes an important tool in any laboratory and facilitates studies of gene regulation and protein function. A plethora of transfection methods have been developed for transfer of DNA into mammalian and animal cells. Those methods either utilize the physicochemical properties of the vector-carrier of the DNA or use mammalian viruses. In the first group of methods, some classic techniques are well-known, such as: calcium phosphate, DEAE-dextran, electroporation liposome-mediated delivery, direct microinjection/biolistic particle delivery, and non-liposomal multi-component reagents. Viral vector systems use both DNA (Adeno-) and RNA (Retro-, Lenti-) viruses. more
