Since their introduction as a life science tool 15 years ago, surface plasmon resonance (SPR) systems have offered highly sensitive, label-free, real-time detection of molecular interactions.

Neuchâtel, Switzerland-based Biacore, which leads the market in SPR instruments, has released a system called the T100, designed both for academic research and drug discovery and development. With a list price of $327,000 (US), the new system incorporates several improvements that distinguish it from its predecessors, the Biacore 2000 and 3000, including new fluidics and software, says Biacore president and CEO Erik Walldén.

Other enhancements include an improved temperature range and the ability to select from four different buffers, features that open up more potential applications and increase throughput, respectively. "Typically, if we want to test the reaction in different buffers, we have to do it one day, and then the next day come in and set up the experiment and...
