Simple Method for Detecting Glycoproteins Dot-blotted or Electro-blotted on to a Polyvinylidene Difluoride Membrane
1a Department of Biological Resource Sciences, Graduate School of Agriculture, Tohoku University.
Abstract:
A simple method is described for detecting glycoproteins which had been dot-blotted or electro-blotted on to a polyvinylidene difluoride (PVDF) membrane after sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis. This method is based on the periodate oxidation of glycoproteins on a PVDF membrane with subsequent staining by the chromophoric hydrazide, 4-N,N-dimethylamino-4'-azobenzene sulfonyl hydrazide. The glycoproteins could be visualized as red-colored spots or bands in the range of 0.16-0.31 μγ.

Western Blotting
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.
Two-dimensional Gel Electrophoresis
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.

Southern Blot
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact...
