Solvents for Crystallization of Proteins
Over the past years a couple of papers were published, in which the use of ionic liquids in biocatalysis and/or the influence of ionic liquids on proteins was described. A very early study from Magnusson et al. described the activating influence of a poor concentration of ethylammonium nitrate [EtNH3 ]+ NO3- on the phosphatase from E. coli .Iborra et al. investigated 2001 the positive influence of different ionic liquids on stability and reactivity of α-chymotrypsine by using a transesterification reaction as an example.In another work, these results were confirmed by fluorescence- and CD-spectroscopy.

Lange et al. reported that ionic liquids accelerate the folding of selected proteins. Recently, MacFarlane et al. demonstrated successfully that a group of biocompatible ionic liquids is in the position to dissolve and to stabilize Cytochrome-C.

Our own research focused on the stabilization and crystallization of enzymes, e.g. using Lysozyme in a number of different ionic liquids.

Our protein-crystallization kit contains 4 typical ionic liquids:
  • 1-Ethyl-3-methyl-imidazolium acetat, >95%
  • 1-Ethyl-3-methyl-imidazolium diethylpohosphat, 98%
  • 1-Ethyl-3-methyl-imidazolium trifluoromethanesulfonat, 99%
  • 1-Ethyl-3-methyl-imidazolium ethylsulfate, 99%
  • 1-Butyl-3-methyl-pyrrolidinium bis(trifluoromethylsulfonyl)imid, 99%
  • 1-Butyl-3-methyl-imidazolium dicyanamid, 98%
  • Triisobutylmethylphosphonium tosylat, 98%
  • N-Butyl-N-trimethylammonium bis(trifluoromethylsulfonyl)imide, 99%
  • Ethanolammonium formiate, 98%
  • Ethylammonium nitrate, 98%
