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.
A benchtop ultracentrifuge, spin columns for the purification of nucleic acids, chromosomal-grade agarose for megabase DNA separations and capillary electrophoresis columns with novel phases – new product ideas in the separation sciences.
Nucleic acid sequence-based amplification (NASBA) is a primer-dependent technology that can be used for the continuous amplification of nucleic acids in a single mixture at one temperature.
Capillary gel electrophoresis with fluorescence detection is a new technique for rapid DNA sequence analysis. The state of this technology and the potential for its future use are discussed.
Over 850 companies will be exhibiting their wares at the Pittsburgh Conference on analytical chemistry and applied spectroscopy, to be held next week in Chicago, Illinois, USA.
Computer algorithms that have been used successfully on protein sequences for the prediction of antigenic T-cell sites have been collected into a single computer software package called TSites.
Shopping for software? DNA ploidy analysis software, PCR primers by design, and a protein modelling package are a selection of this week's scientific software highlights.
A protein visualization system to view protein bands as they separate and a programmable power supply that plots run parameters in real time for troubleshooting purposes — new product highlights for electrophoresis.
A kit to avoid false positives with PCR and YAC vectors will feature at next week's Miami Bio/Technology Winter Symposium on the Molecular Biology of Human Genetic Disease to be held in Miami, Florida.
