Scientists from Baxter Laboratories have developed an in vitro skin test that could work alongside other alternative methods to help replace animals such as rabbits and guinea pigs in testing for cosmetics and pharmaceuticals.
The Biotage Extrahera is an automated system for the processing of supported liquid extraction (SLE) and solid-phase extraction (SPE) methods in both plate and column formats, making the system a flexible option for a wide variety of analytical laboratories.
Isothermal titration calorimetry (ITC) enables label-free measurement of binding events by measuring the heat released or absorbed during biochemical binding. Requiring no assay development, the MicroCal iTC200 provides results quickly and is a suitable tool for any research laboratory studying biomolecular interactions.
Forensic scientist Anna Bradley is undertaking the world's largest bullet lead study, building on research the FBI started when US President John F Kennedy was assassinated in 1963. Bradley is looking to track the unique 'fingerprint' of bullets in the hope of solving crimes.
Asynt announces PressureSyn, a 125 mL working volume high-pressure reactor that combines good performance, ease of use and a high level of operational safety.
Previously, to test for the presence of milk allergens, one had to decide whether to look for casein or Beta-lactoglobulin as an indicator for allergenic residues. With the AgraStrip Total Milk, the user can test for both at the same time.
In an effort to investigate the reactions taking place in a biological cell, scientists tried to replicate them in an artificial cell. Such experiments have so far worked with very simple reactions, but the team managed to establish a complex biochemical reaction in tiny droplets only a few micrometres in size.
Researchers have discovered that by compressing sodium chloride (rock salt) under certain high-pressure conditions, they can trigger a process which was found to form new compounds - despite chemistry textbooks saying this is impossible.
With a 3D printer, open-source software and free digital designs, cash-strapped scientists can now fabricate their own lab equipment at a fraction of the cost.
The Patch Test Kit (or Portable Contamination Analysis Kit) is a tool for identifying and monitoring the types and levels of particulate contamination in all fluid power systems, including those offshore where water-based fluids are utilised.
An African medicinal plant - Nauclea latifolia (also known as the pin cushion tree) - has been found to produce large quantities of molecules with analgesic properties. Even more surprising, analysis shows that the molecule is identical to the heretofor wholly synthetic painkiller Tramadol.
The WaterTest Kit is used for the quantitative determination of water content in % of mineral and lubrication oils. The simple addition of two reagents to the contaminated oil causes an increase of pressure in the measuring cell. This pressure increase is read off via the digital display as water content in % or ppm.
Professors Stephen Trumble and Sascha Usenko, of Baylor University, have developed a new method to determine the lifetime chemical profiles of blue whales. As revealed in the journal Proceedings of the National Academy of Sciences, the scientists found the answer in the whales’ earwax plugs.
University of Waikato Biological Sciences Professor Vic Arcus and his research group have been awarded $850,000 for a two-year project to develop a new method for designing ‘next-generation enzymes’ for commercial use.
Until now, only 36 basic types of chemical reactions have been identified. But a 37th type has just been added to the list.
