Description

Application

Periodic acid is commonly used as a component for glycoprotein stains. Selective staining of glycoproteins on SDS-PAGE and membranes is carried out using a modification of the Periodic Acid-Schiff (PAS) method. Staining of sugar moieties of glycoproteins yields magenta bands with a colorless background. The Periodic Acid/Schiff Reagent stains vicinal diol groups found mainly on peripheral sugars and sialic acids and is used as a general glycoprotein stain. Periodic acid is also used to cleave reversible cross-linkers (e.g. DATD, DHEBA) in PAGE gels.

Analysis Note

Tested for use in staining of glycoproteins.
