Product Information

Lanthanide scale-up phasing compounds (ref.: CSM002-0101A to CSM002-0110A)

Lanthanide derivatives are obtained with these compounds, either by soaking or by co-crystallization, into crystals of biological macromolecules. The crystal derivatives thus obtained can be used to solve the structure of biological macromolecules by using structure-determination methods taking advantage of the strong anomalous signal of lanthanides in their LIII absorption edge or, for some of them, with radiation from a lab X-ray source. Derivative based on Eu atom (LIII abs. edge: 6977 eV) or Yb atom (LIII abs. edge: 8944 eV) are available. We propose these compounds individually in larger quantity than in the phasing kit, for the refinement of a promising derivative.
