The silica gel acts as the stationary phase and the solvent mixture acts as the mobile phase. In the ideal solvent system the compounds of interest are soluble to different degrees. Separation results from the partition equilibrium of the components in ...

Thus, after Orcinol staining, the glycosynthase reaction product is hidden behind the dominating spot of residual unreacted β-L-fucopyranosyl azide.
