The BioStar OIA CdTOX AB assay is an immunoassay test for the rapid qualitative detection of Clostridium difficile Toxins A and/or B in human faecal samples from patients suspected of having CDAD. Toxin A is an enterotoxin which appears to be responsible for the clinical symptoms of diarrhoea and colonic inflammation, while Toxin B is responsible for the associated cell destruction. Clinical symptoms of CDAD were once thought to be solely due to Toxin A; however, there is growing evidence that Toxin B may also play an important role in the pathogenesis of C. difficile. In many markets it is mandatory to use a test that detects both toxins, therefore a test which detects both toxins would be an aid to prompt diagnosis and allow the physician to initiate appropriate patient management.
Biomek 3000 GeXP Methods for automated gene expression sample preparation is a software plug-in that provides methods to prepare samples for the GenomeLab GeXP Genetic Analysis system on the Biomek 3000 Liquid Handling Workstation. The suite includes fully validated methods for RNA sample prep, quantitation and normalisation and reaction set-up. When used together, the Biomek 3000 workstation and these validated methods along with the GeXP Genetic Analysis system deliver a complete solution for gene expression analysis, from sample to answer.
Rockeby Biomed has received the European approval, CE Mark, for its Human Antigen Detection Test for Influenza A.
Research into the ancestry of US President, Thomas Jefferson has thrown new light onto his ancestry and the migration of a rare class of DNA.
HDACs are typically found in multiprotein complexes and are tightly regulated by subcellular localisation, phosphorylation, and likely by other mechanisms.
The iBlot Dry Blotting System efficiently and reliably transfers proteins from polyacrylamide gels in seven minutes or less without the need for buffers or an external power supply.
An Australian study has been the first to prove conclusively that there is no single gene for eye colour.
Researchers have constructed a protein out of amino acids not found in natural proteins, discovering that they can form a complex, stable structure closely resembling a natural protein. Their findings could help scientists design drugs that look and act like real proteins but won't be degraded by enzymes or targeted by the immune system, as natural proteins are.
Designed for use with several Thermo UV/vis spectrophotometers, including the Spectronic BioMate 3, the Spectronic Genesys 10 Bio, and the Evolution 300, the nanoCell accessory offers sub-microlitre analysis capabilities for DNA and protein analysis in the life science laboratory. The nanoCell allows users to obtain the maximum amount of information from minute sample volumes. This is especially critical in laboratories performing assays for nucleic acids, RNA/DNA and protein concentrations that wish to limit the amount of sample used for analysis.
Varian has announced an improved version of the OnSite OraLab oral fluid drug testing device. Featuring a proprietary detection methodology, the OraLab is more accurate and achieves lower detection limits for parent-THC than previous devices. OraLab is an extension of Varian''s drugs of abuse oral fluid testing product line that offers devices for both on-site and laboratory-based testing.
BOC Edwards has launched a temperature-controlled evaporation source for depositing the sensitive materials used in the research and production of organic light emitting diodes (OLEDs) and solar cells. The source gives electronics manufacturers and industrial researchers accurate control of the temperature profile, and therefore greater control of the deposition rate, reducing wastage of material and associated costs.
