Mitegen XP Screen: Protein Crystal Glue, 96 Solutions (1.7mL Each), Enhanced with Anderson-Evans Polyoxotungstate for Crystallization
Supplier: Mitegen MCS350
The XP Screen, also known as "The Protein Crystal Glue," provides 96 prominent crystallization conditions, each containing 1.7 ml of solution. This advanced screen is uniquely formulated with the Anderson-Evans polyoxotungstate [TeW6O24]6− (TEW) at a 1 mM final concentration. TEW is a powerful additive proven to significantly promote crystal contacts and improve overall crystal quality, crucial for high-resolution studies. A key advantage of this polyoxotungstate is its ability to provide a valuable anomalous signal for phasing, attributed to its six tungsten atoms, streamlining the structural determination process. Optimized for TEW stability, the XP Screen enhances crystallization and crystal diffraction quality, particularly for challenging protein targets. TEW has been shown to covalently bind to protein molecules and act as a molecular linker, aiding diverse crystallization outcomes.
