For the lab — a nitric oxide analyser, a ratio imaging microscope system for the life sciences, a device for producing digital images from slides, hyphenated systems and a selection of detectors.
Research tools for the immunologist include a new class of mitochondrion-selective fluorescent dyes, ELISAs for urokinase-type plasminogen activator and cathepsin D and a host of antibodies and reagents.
Products to meet your amplification needs include a device for polymerase chain reaction (PCR) quantitation, reagents for the isolation, extraction and purification of DNA, kits, gels, thermal cyclers and laboratory consumables.
Cell and tissue culture aids featured this week include postmitotic human neuronal cells, viability test kits for yeast, fungi and bacteria, cultureware, bioreactors, platers, shakers, stirrers and workstations.
Software and hardware options featured this week include programs for data acquisition, management and analysis, imaging and molecular biology, and a selection of new computer systems.
New in the marketplace this week—recombinant firefly luciferase, a new fluorescent reagent for fatty acid analysis, fluorescently labelled tubulin and an assortment of hardware options.
New in the microscopy/image analysis marketplace — a transmission electron microscope for the non-specialist, an advanced fluorescent in situ hybridization system and an upgraded version of software for intracellular ion imaging.
New reagents to watch out for include ‘live’ cell nucleic acid stains, a yeast transformation kit, a chemiluminescent immunoblotting system and an expression system for the production of soluble proteins in E. coli.
New tools for the chromatographer include an analytical workstation for the characterization and analysis of biomolecules by immunoassay and chromatography, and an assortment of columns, pumps, detectors and accessories.
Highlighted this week — a handy device for replica plating microbial colonies on solid growth media, a kit for the direct colorimetric detection of hepatitis B DNA and a nonradioactive reverse transcriptase assay for the detection of HIV-1.
Products from the molecular biology marketplace include nuclear extracts for gene regulation studies, a kit for purifying DNA from tissue and mouse tails, and one for the in vitro packaging of DNA from bacteriophage lambda.
Digital imaging spectrophotometers can simultaneously measure the spectra of hundreds of features in a two-dimensional scene. While a variety of applications can be anticipated, a colorimetric analysis of mutants expressing pigmented proteins has already led to the development of efficient algorithms for optimizing combinatorial mutagenesis.
Featured this week—a red blood cell agglutination reagent, an agar substitute, antibodies to markers of metastasis and a scanning probe microscope for imaging cells and tissues in situ with nanometre resolution.
