New Crystallization Robot Oryx 8 @ CNR-IBPM!

The Oryx 8 Crystallization Robot is a product of Douglas Instruments and is designed for protein crystallization. It is capable of setting up sitting drops with volumes ranging from 100 + 100 nl to 2 + 2 µl for 96 wells. For hanging drop experiments, up to five drops can be set up per cover slide, with volumes up to 8 + 8 µl. The Oryx 8 uses multi-bore dispensing tips (microtips), which have several independent channels to dispense small volumes. Each channel dispenses a different solution, and the solutions mix in the drop after they are dispensed. This system is ideal for microseeding experiments as the microtip always touches the plate when liquids are dispensed. Moreover, the Oryx 8 is equipped with two chassis and can use 3, 4, and 7-bore microtips. Large volumes, including oil for microbatch experiments, are dispensed by the right-hand arm using the large (2 ml) motorized syringe.The Oryx 8 is known for its versatility and minimal waste of protein solution, making it a preferred choice for protein crystallization.

New Cryoprobe @ CERM!

A new cryoprobe has just arrived!! It is a QCI-P cryoprobe that allows the excitation of four nuclear spins, including 1H, 13C, 15N and 31P.

It will also find useful applications for in-cell NMR by monitoring 31P signals in parallel to 2D 1H-15N experiments.

New Endor module @ CERM!

The ENDOR module for our EPR spectrometer has arrived. ENDOR is an EPR experiments that relies upon the excitation of nuclear spins to reveal spatial proximity between the unpaired electron and those nuclei.

This setup will enable the implementation of state-of-the-art experiments to characterize the structure of the metal centers of metalloproteins. ENDOR is also complementary to DEER, because it enables distance measurements with site-selective tags containing 19F.
