Influence of divalent cations in the protein crystallization process assisted by Lanthanide-based additives.

The use of lanthanide complexes as powerful auxiliaries for biocrystallography prompted us to systematically analyze the influence of the commercial crystallization kit composition on the efficiency of two lanthanide additives: [Eu(DPA)3]3- and Tb-Xo4. This study reveals that the tris-dipicolinate complex presents a lower chemical stability and a strong tendency to... Show more
