title: Elution of glycoproteins from replicas of sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels.
abstract: A method for the elution of glycoproteins from sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) replicas of gels on polyvinylidene difluoride (PVDF) membranes is described. Ten model glycoproteins were resolved by SDS-PAGE and then electrotransferred onto PVDF membranes. After reversible staining, glycoprotein bands were eluted with a mixture of SDS/Triton X-100 at pH 9 or with a mixture of guanidinium hydrochloride/lysophosphatidylcholine at neutral pH. For both types of eluents, the final recoveries ranged from over 30% to about 80%. Good recoveries and mild conditions of elution render the method applicable for the structural elucidation of glycan chains.
