MicroED Stage Controller
About the Innovation
MicroED is a recently developed method from the Gonen lab which allows the collection of high-resolution electron diffraction data from extremely small protein microcrystals using an electron cryo-microscope (cryo-EM).
For MicroED, the standard transmission electron microscopy (TEM) equipment is used with one modification: use of a constant rotation-controlling device, the MicroED Stage Controller.
The normal operating control on TEM equipment uses pressure-sensitive resistors to provide manual control. An adapter brings those control signals out to an external enclosure, where the operator can operate the system normally by feeding the pressure-sensitive resistor signals back into the increment/decrement circuits, or with standard potentiometers switched into the circuit instead of the pressure-sensitive controls. There are separate controls for increment and decrement rates that mimic a constant pressure on the built-in control.
For use specifically in a MicroED experiment using a cryo-EM microscope.
Designs are available for free use for Non-Profit Research (no support is offered). Commercial Licenses are also available.
