The Nunc 1536-Well High Base Plates are designed for high throughput screening laboratories. The plate's height provides a large area for secure plate gripping by automated systems and for applying barcode labels. These plates are suitable for cell culture analysis or assays involving luminescence, fluorescence or colorimetric reactions.
The Hitachi L8900 series dedicated amino acid analyser boasts refinements for fast analysis with high detection limits. Improvements include new hardware, a more efficient pump and a re-engineered direct injection auto sampler, all complemented by the powerful and user-friendly EZChrom chromatography data system.
Laser tweezers are non-contact tools that use light to trap, move and fuse particles, cells or organisms. An infrared laser beam is focused through an objective lens to create an intense optical radiation field. The resulting photon pressure at the surface of the particle or cell enables the operator to move the cells at will, sorting, separating or collecting the cells as required. By combining the system with an ultraviolet laser, cells can be cut free of surrounding structures enabling micro dissection. Where two cells have been trapped by the laser tweezers, the ultraviolet laser can be used to cut the cell membranes allowing the cells to fuse together. A similar process enables operators to insert particles into the cell, for example fluorescent beads, or to perform targeted transfection into the cells of DNA or proteins.
An alliance between Dharmacon and 14 international research centres have announced their progress towards their fundamental goal of developing internationally accepted standards for conducting research using the first complete siRNA library.
When sexual species reproduce asexually, they accumulate bad mutations at an increased rate, report two Indiana University evolutionary biologists. The researchers used the model species Daphnia pulex, or water flea, for their studies
Scientists have used mass spectrometry for decades to determine the chemical composition of samples but rarely has it been used to identify viruses, and never in complex environmental samples.
The Atlantis microtitre plate washer from ASYS Hitech (Austria) has automated and affordable aspiration and dispensing facilities for 96 or 384 well plate analysis to suit all laboratories using microtitre plates for routine assays.
Sigma-Aldrich has introduced TargeTron vectors designed for use with the TargeTron gene knockout system. The vectors enhance the capabilities and increase the flexibility of the system providing researchers with a targeted method to knock out multiple genes in prokaryotic organisms, to generate knockouts without using selection or by using removable selection and to produce knockouts in organisms lacking a source of T7 RNA polymerase.
A publicly-available microbial database tyo host a range of microbial genome sequences has been launched by researchers at the Virginia Bioinformatics Institute at Virginia Tech.
The expiry of the Polymerase Chain Reaction Patent should foster the development of a range of innovative tests and kits and lead to a reduction in the costs of PCR reagents and instrumentation
The University of Auckland's Faculty of Science's Dr Alexei Drummond has been part of a global research team analysing the genetic sequences of viruses in animals.
