Abstract
- Half maximal inhibitory concentration (IC <subscript>50</subscript> ) is a measurement often used to compare the efficiency of various carbohydrates and their derivatives for inhibition of lectin binding to particular ligands. IC <subscript>50</subscript> values can be calculated using experimental data from various platforms including enzyme-linked immunosorbent assay- (ELISA-)type microtiter plate assays, isothermal titration calorimetry (ITC), or glycan microarrays. In this chapter, we describe methods to fluorescently label a lectin, to carry out a lectin binding inhibition experiment on glycan microarrays, and to calculate the IC <subscript>50</subscript> value of a binding inhibitory molecule using GraphPad Prism software. In the example used to illustrate the method in this chapter, IC <subscript>50</subscript> calculation is demonstrated for inhibition of Maackia amurensis agglutinin (MAA) binding to 3'sialyl-N-acetyllactosamine (3SLN) using free lactose.<br /> (© 2022.
