COVALENT ATTACHMENT OF PEPTIDES TO MEMBRANES FOR DOT-BLOT ANALYSIS OF GLYCOSYLATION SITES AND EPITOPES

Noncovalent binding of proteins to membranes is often employed for dot-blot analysis with various visualization techniques. These techniques are usually not applicable to peptide dot-blot analysis due to peptide wash-off during the staining procedure. As exemplified with a synthetic peptide and peptides produced by proteolysis of a protein, it is possible to achieve efficient covalent attachment to Immobilon-AV membranes. The utility of this membrane has been demonstrated with immunostaining and carbohydrate staining procedures. © 1993 Academic Press, Inc.
