Mitegen XP Up Screen Crystallization Screen, For High TEW Concentrations, 96 Solutions (1.7mL Each), Flexible TEW Addition
The XP Up Screen Crystallization Screen is uniquely optimized for exploring protein crystallization with high concentrations of the Anderson-Evans polyoxotungstate (TEW), specifically up to 10 mM. This screen provides 96 prominent crystallization conditions, each containing 1.7 ml of solution, offering significant flexibility for optimizing challenging targets. TEW is a powerful additive known to promote crystal contacts, improve crystal quality, and provide a valuable anomalous signal for phasing due to its six tungsten atoms. Experiments have shown that higher TEW concentrations (5-10 mM) can significantly increase crystallizability. For maximum flexibility, TEW is supplied in a separate tube, allowing users to add it to the protein droplet at their desired final concentration. Each kit includes 5 mg TEW (X-TEW-5) for preparing a 100 mM stock solution. Ship at ambient temperature, store at 8-10°C, with a 12-month shelf life.

If using FURA 2 and BCECF, which are both excitation dyes, one drive unit (P/N L2250146) is required to fit on both pairs of filters. Both dyes can be monitored in the same experiment. If using INDO-1 and BCECF, two drive units are necessary- one for excitation and one for emission.
