Martin lab designed and constructed first quadruple-resonance probe

graphical abstract
Fri, Dec 1

The Martin Lab has published a paper describing the first quadruple-resonance (1H/13C/2H/15N) probe for a 800 MHz magnet. The probe utilizes a coaxial coil design with an outer modified Alderman-Grant coil for the proton channel and inner variable-pitch solenoid for the heteronuclear channels; homebuilt coaxial transmission line segments are used as discrete circuit elements to allow high power handling. The inclusion of a high-power deuterium channel allows greater utilization of the deuteration common in biomolecular solid-state NMR, enabling direct observation of local order and mobility. The fourth channel allows for new three-dimensional experiments to determine structure and observe dynamics in biomacromolecules.
