    • Langmuir isotherms require the use of concentrations of "free" ligand in solution,. Nevertheless, due to the range of low affinities accessible by STD NMR spectroscopy, the "total" concentration of ligand can be used instead, without introducing large errors in the determination of affinities

    • In contrast to the WGA-ligand systems, in this case, at ligand concentrations above 1 mM, nonspecific behavior of the binding was observed from the isotherms (see the Supporting Information). Fortunately, the quality of the data in the initial growing region of the curve allowed a quantitative analysis satisfactory enough as to give good mathematical fitting to a one-site Langmuir binding isotherm equation

    • Herein, we have used an exponential equation for the determination of the STD initial slopes, but the initial growth rates could also be obtained by linear regression analysis using short saturation times, if linearity is assured
