XP Screen: The Protein Crystal Glue 96 solutions (1.7 ml each)

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[1].
Optimized for TEW stability, the XP Screen improves crystallization and crystal diffraction quality of challenging targets.

XP Screen：The Protein Crystal Glue 96 溶液（每种 1.7 毫升）
XP Screen 提供了 96 种最突出的结晶条件，使用 1 mM 终浓度的 Anderson-Evans 多氧钨酸盐 [TeW6O24]6- (TEW) 升级。 事实证明，这种添加剂可以促进晶体接触，提高晶体质量，并由于 6 个钨原子而进一步为定相提供有价值的异常信号 [1]。
XP Screen 针对 TEW 稳定性进行了优化，可提高具有挑战性的目标的结晶和晶体衍射质量。

The XP Screen provides 96 crystallization conditions upgraded with the Anderson−Evans polyoxotungstate [TeW6O24]6− (TEW) (available here) 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.

TEW was shown to:

  • covalently bind and structurally adapt to fit into protein molecules (cgAUS1, PDB code: 4Z12, 4Z13)[2]
  • act as linker in various orientations and thereby create either smaller (abPPO4, PDB code: 4OUA) or larger (lysozyme, PDB code: 4PHI) protein-protein distances[3,4]
  • induce heterogeneous crystallization of two different protein forms in one single crystal (abPPO4, PDB code: 4OUA)[4]

Our new XP Screen contains TEW in 96 of the most prominent crystallization conditions, providing an environment for TEW to improve crystallization and crystal diffraction quality especially for challenging targets.

规格
XP Screen 提供 96 种结晶条件，使用 1 mM 终浓度的 Anderson-Evans 多氧钨酸盐 [TeW6O24]6- (TEW)（可在此处获得）进行升级。这种添加剂已被证明可以促进晶体接触，提高晶体质量，并由于 6 个钨原子进一步提供用于定相的有价值的异常信号。

TEW 被证明：

共价结合并在结构上适应以适应蛋白质分子（cgAUS1，PDB 代码：4Z12、4Z13）[2]
作为各种方向的连接器，从而产生更小（abPPO4，PDB 代码：4OUA）或更大（溶菌酶，PDB 代码：4PHI）的蛋白质-蛋白质距离[3,4]
在一个单晶中诱导两种不同蛋白质形式的异质结晶（abPPO4，PDB 代码：4OUA）[4]
我们新的 XP Screen 在 96 种最突出的结晶条件下包含 TEW，为 TEW 提供了一个环境，以改善结晶和晶体衍射质量，尤其是对于具有挑战性的目标。
