Highly Sensitive Method for Specific, Brief, and Economical Detection of Glycoproteins in Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis by the Synthesis of a New Hydrazide Derivative

A new hydrazide derivative was synthesized and used for the first time as a specific, brief, and economical probe to selectively visualize glycoproteins in 1-D and 2-D sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) with high sensitivity. The detection limit of the newly developed staining method is 2- and 4-fold higher than that of the widely used Pro-Q Emerald 300 and 488 stains, respectively.
