摘要

Use of lanthanide(III) complex compound (I) for resolution of three dimensional structure of a protein entity by X-ray diffraction in crystallography, is claimed. Use of lanthanide(III) complex compound of formula (I) for resolution of three dimensional structure of a protein entity by X-ray diffraction in crystallography, is claimed. R : -COO - or -A-X; A : -(CH 2) n- chain optionally substituted with one or two -CH 3 groups; X : -OH, -COO - or -NH 3 +; R : -[(CH 2) mNR1R2(CH 2) pOH] +; R1, R2 : H or CH 3; Ln1 : lanthanide, preferably Sm, Eu, Gd, Lu, Tb, Ho, Er, Tm or Yb; and n, m, p : 1-4. Independent claims are included for: (1) lanthanide(III) complex compound of formula (I); and (2) a substitited 4-[1,2,3]triazol-1-yl-pyridine-2,6-dicarboxylic acid compound of formula (II). R1 : -COOH or -A-X1; and X1 : -OH, -COOH or -NH 2. [Image] [Image].
