text: *X-ray crystallography
  Just like other organic molecule study, X-ray crystallography is a very useful tool to know the detail information on the interaction between carbohydrate and protein.
  *NMR Study
  By using titration, NOESY(Nuclear Overhauser Effect SpectroscopY), CIDNP experiments, the specificity and affinity of binding, association constants and equilibrium thermodynamic parameters of carbohydrate–protein binding can be studied.
  *Molecular Modeling
  In many cases, the conformation information is required, however, sometimes it is not able to get directly from the experiments. So the knowledge-based model building approach is used.
  *Fluorescence Spectrometry
  Fluorescence spectrometry is a useful tool and has its advantages: no procedure for separation and plenty of ways to get fluorophore source: there are some of amino acids and ligands that have fluorophore after they are activated.
  *Dual polarisation interferometry
  Dual polarisation interferometry is a label free analytical technique for measuring interactions and associated conformational changes.
