A sensitive, high-throughput fluorescent DNA analyser has been developed that uses sheathflows of buffer around each element in an array of gel capillaries.
Research tools for the molecular biologist featured this week include paints for the detection of human chromosomes 11 and 12, a kit for isolating differentially expressed genes, gel chambers, gels and other paraphernalia.
An automated approach for partial sequence analysis of entire cDNA libraries is described with the immediate aim of generating an expressed sequence catalogue and the long-term goal of sequencing by hybridization.
Featured this week are products designed to automate laboratory tasks, including an instrument for processing western blots, an infrared fluorescence-based sequencer and robotic liquid handling systems.
Fundamental information that enhances our understanding of biospecific interactions can be obtained using a new analytical system based on biosensor technology. The functional characteristics of biospecific interaction, such as kinetics, affinity and binding position, are examined by label-free analysis of proteins in free solution binding to an immobilized ligand at a hydrophilic sensor surface.
Sequence analysis software, structure prediction programs, columns and media, and a range of products for glycobiology research — new products for a new year.
