• PubMed Abstract: 
  

  New trisdipicolinic acid-lanthanide complexes are reported as phasing agents for X-ray crystallography of proteins. It is demonstrated that CuAAC modifications allow protein co-crystallization with low concentration of lanthanide complexes leading to an accurate structure determination.
