This week's labelling technology product line-up includes reagents for three-colour cell analysis kits, for end-labelling oligos and an ethidium bromide stain substitute.
An automated DNA sequencing system, the collaborative effort of Japanese scientists and engineers, which has a potential output of up to 108,000 bases per day is described.
Handy helpers in this week's issue include a dual-purpose device for vertical electrophoresis and electroblotting, a triple-tray gel box and news of a new patent sequence data bank.
By combining small colloidal gold probes with video-enhanced quantitative microscopy, the intracellular dynamics of specific proteins in living cells can now be studied.
Focusingthisweekon microscopy and image analysis, new products include a hand-held microscope, a new objective that converts a standard microscope to a fluorescence microscope, and a DNA sequence gel reader with voice recognition.
Stock up your shelves with the latest biochemicals and reagents to come off the production line, including new phage lambda cloning vectors, a genetically-engineered substrate for receptor-specific mammalian cell attachment, and a kit for detecting Mycoplasma contamination in cell lines.
Protein engineering has made it possible to combine the binding sites of murine antibodies with human antibody regions. Antibodies constructed in this way have important advantages for therapy.
Neuropeptide Y antiserum for immunohistochemical use, a monoclonal antibody to cytokeratin 20 and a range of fluorescent microspheres for antibody attachment – new products for today's immunologist.
Over 3,000 exhibitors will be showing off their wares at ACHEMA 91, an international meetingon chemical engineeringand biotechnology to be held in Frankfurt, Germany, 9–5 June.
Displacement chromatography is a multicomponent preparative chromatographic technique that enables simultaneous concentration and purification of biomolecules.
This week's look at what's new for the chromatographer features software that is designed to take the guesswork out of HPLC methods development and a high-capacity autosampler with refrigeration option for thermally-sensitive samples.
Infrared signals of microorganisms are highly specific fingerprint-like patterns that can be used for probing the identity of microorganisms. The simplicity and versatility of Fourier-transform infrared spectroscopy (FT-IR) makes it a versatile technique for rapid differentiation, classification, identification and large-scale screening at the subspecies level.
A monoclonal antibody to Heliobacter spp./Campylobacter spp., colony counting systems and a pocket-sized microscope for on-the-spot analysis — product news for the microbiologist.
Perfusion chromatography is a technique based on fluid dynamics for reducing stagnant mobile phase mass transfer in liquid chromatography. This is achieved by using supports with large pores that allow mobile phase to flow through particles.
Oligonucleotide analogues offer several mechanisms for potential therapeutic action; triple helix agents that inhibit disease-causing genes at the DNA level show particular promise.
A new reagent for on-column biotinylation of oligonucleotides, a neurotoxic peptide antagonist at brain NMDA receptors and systems for multiple peptide synthesis are included in this week's review.
