It seems, that the direct application of the principle to chromatogram monitoring is unpracticable due to the number of variables involved. The main emphasis then lies in the "new" way of employing gas-liquid partition.EeroHaahtiandHans
g., liquid chromatography and mass spectrometry, it enables rapid and high-sensitivity profiling of complex glycan features without the need for liberation of glycans. Target samples include an extensive range of glycoconjugates involved in cells, tissues, body fluids, as well as synthetic glycans ...
Proteins were purified by NTA affinity chromatography, taking advantage of the presence of a His-tag at the C-terminal. Protein solutions were prepared by exhaustive dialysis against 50 mM HEPES buffer and protein concentrations were determined spectrophotometrically using a known value of the ...
