Molecular-Dynamics Simulation Methods for Macromolecular Crystallograhy

Molecular-dynamics simulation methods for macromolecular crystallography

Image Source: Wych et al. (2023). Acta Cryst. D79, 50-65,

In a paper at Acta Crystallographica Section D, David C. Wych et al. evaluate the potential benefits of molecular-dynamics (MD) simulations for macromolecular crystallography (MX). This was done by performing "room-temperature X-ray diffraction studies of the catalytic subunit of mouse protein kinase A (PKA-C)" And then comparing this to crystalline MD simulations of PKA-C.

"The results led to the development of an MD-MX analysis procedure and several associated methods." "Based on the benefits seen applying these methods to PKA, they recommend incorporating their MD-MX procedure into MX studies, to decide among ambiguous interpretations of electron density that occur, inevitably, as part of standard model refinement." 1

Cryogenic Storage and Shipping Solutions

When working with samples, you'll need to store and most likely ship them for analysis. To help you with this we offer two of the most popular storage and shipping solutions available. These are the HC34 freezer for storage and the CX100 dryshipper with upright shipping case for transport. Learn more about each below. 

HC34 Freezer

HC34 Freezer

The HC34 is a high capacity LN2 freezer designed for longer term storage of your samples. It will hold 6 MiTeGen puck storage canes. A roller base for easy movement in the lab as well as an alarm is available.

APS Upgrade Shutdown - Alternative Beamlines

APS Upgrade Shutdown - Find Alternative Beamlines

Are you a user of the APS (Advanced Photon Source) beamlines? As you know the beamlines at APS will be shutdown for an entire year to make way for upgrades. We can help you find an alternative beamline for your research as well as get you equipped to conduct your research there. Reach out to us and let us help you get up and running at an alternative beamline.
