Attana AB in 2007

Attana AB, a leading supplier of affordable label-free biosensor systems for real-time detection and analysis of molecular interactions, will be participating in various antibody and diagnostics conferences and exhibitions early this year. Attana is a proud corporate supporter of The Protein Engineering Summit (PEGS) which will be held in Boston, Massachusetts, USA, this May 14th – 18th, 2007. Representatives from Attana will be exhibiting the new A100 C-Fast system throughout the duration of the PEGS Summit at booth number 24. Attana will showcase their latest automated system at the British Society for Immunology Glasgow 2007 conference between February 20th and 23rd, 2007. They would be situated at booth number 9. In addition Attana will be present at the 3rd Halle Conference on Recombinant Protein Production in Germany. Attana representatives will be participating in this conference as delegates and will be open to discussions about the latest A100 C Fast systems and more. Based in Stockholm, Sweden, Attana AB was founded in 2002 with the goal of becoming a world leader within sensor technologies for detecting, registering and measuring chemical and biochemical reactions, based on the Quartz Crystal Microbalance (QCM) technology. Today, Attana develops and sells the A100 biosensor along with consumables and associated services throughout Europe. Attana’s systems are employed by leading universities and biotech companies within application areas ranging from drug discovery to surface science, yet all with a common goal: understanding molecules. ABOUT Technology Quartz Crystal Microbalance (QCM) can be explained as a very sensitive scale or balance, which can measure atomic changes in mass. QCM uses the piezoelectric effect of quartz crystals, by applying an AC-potential to oscillate a quartz crystal. When atoms or molecules are added to, or removed from the surface, the change in the resonance frequency can be converted to a mass response. By attaching a specific molecule (the target) to the surface of the crystal and letting a sample flow over the surface, the target’s interaction with the sample can efficiently be studied. QCM can thereby be used to detect the presence of a substance or to characterise biochemical reactions, e.g. a drug candidate’s interaction with a protein.
