The XP Screen provides 96 of the most prominent crystallization conditions upgraded with the Anderson−Evans polyoxotungstate [TeW6O24]6− (TEW) at 1 mM final concentration. This additive has proven to promote crystal contacts, improve crystal quality and further provides a valuable anomalous signal for phasing due to 6 tungsten atoms.
Optimized for TEW stability, the XP Screen improves crystallization and crystal diffraction quality of challenging targets.
