XP Up Screen

SKU: orb762351

Description

The additive Anderson-Evans polyoxotungstate (TEW) [TeW6O24]6− has been shown to promote crystal contacts, improve crystal quality, and provide a valuable anomalous signal for phase determination due to its 6 tungsten atoms. It has successfully induced protein crystallization even at low concentrations of 1 mM. However, our own experiments have shown that a higher concentration of 5 or 10 mM TEW can significantly increase crystallizability even further.\nThe XP Up Screen offers 96 of the most common crystallization conditions that have been proven to be successfully improved with up to 10 mM TEW. To offer complete flexibility in terms of final concentration, TEW is provided in an additional tube and only needs to be added to the protein drop. The solutions are stable in the long term in the presence of up to 10 mM TEW, thus enabling maximum flexibility without compromise.
