More crystals through XChem

Following an early commissioning stage, XChem crystallised its core xray collection protocol as 180 degrees rotation in 60 seconds, which provides PanDDA with good datasets. But what has never been fully characterised is the lowest dose per crystal required for PanDDA to work. XChem now has an established hit rate profile where, based on our Read More …

How high throughput fragment screening is reviving old school crystallography tricks

Takeaway: Why: we need lots of well diffracting crystals. How: crystallisation growth optimisation. What: tweaking conditions, phase space understanding, seeding, MMS. At this day and age (2018) many people are thinking that the future of structural molecular biology being about serial XFEL or synchrotron crystallography and electron diffraction, which are great tools to harness the Read More …
