The world's most powerful NMR spectrometer

The most powerful, high-resolution nuclear magnet resonance (NMR) spectrometer ever constructed was delivered today to The Scripps Research Institute (TSRI). According to Peter Wright, Ph.D., Chairman, Department of Molecular Biology, the new NMR, referred to by the frequency at which it operates, 900 MHz, will become the centerpiece of one of the world's most prominent collections of NMR instruments.

Wright commented, "It's fantastic. The capabilities of this instrument take us to a new level."

The instrument is the first of its kind and has been several years in the making by its German manufacturer, Bruker Instruments, Inc.

TSRI is a leader in high-powered NMR instrumentation, with 10 instruments at or above 500 MHz. Wright continued, "It's a very big deal to have the first major instrument of this type in this city. It reinforces our position at the leading edge of molecular and structural biology."

NMR spectroscopy is a diagnostic tool for chemistry and biology; additionally, it forms the basis for the technique of magnetic resonance imaging (MRI) in medicine. In a research context, NMR provides atomic coordinates of a wide range of biologically important molecules in solution. This information enables scientists to determine the structure-function relationships of molecules that lie at the heart of understanding fundamental biological processes.

Determining the three-dimensional structures of proteins and nucleic acids provides important insights into the basic questions about how living organisms function and change, and how particular alterations can lead to human disease. Structural biology is seen by scientists as particularly important in today's research environment: while the genomes of humans and several other organisms have been solved, the structures of most of the proteins which the tens of thousands of genes encode remain a mystery.

In an NMR experiment, a sample in a long tube is inserted into the magnet, which cons
