Here, we describe a simple and sensitive method that allows fluorescent detection of glycoproteins on polyvinylidene difluoride (PVDF) membrane. We used periodic acid oxidation of carbohydrate chains of glycoproteins and fluorescent labeling with 8-aminonaphthalene-1,3,6-trisulfonate (AN-TS) by reductive amination. We developed an additional method to enhance the ability of PVDF to absorb glycoproteins by using non-glycoprotein lectin, such as wheat germ agglutinin (WGA), as a link between the PVDF membrane and glycoproteins, resulting in considerably increased detection sensitivity to glycoproteins.
