Mitegen ANDERSON-EVANS POLYOXOTUNG 5MG
Anderson-Evans polyoxotungstate, 5 mg.The Anderson−Evans polyoxotungstate [TeW6O24]6− (TEW) is a universal and flexible additive for protein crystallization. With its planar structure and high negative charge, it has proven to promote crystal contacts, improve crystal quality and further provides a valuable anomalous signal for phasing due to 6 tungsten atoms[1].
