Description
The kit provides three essential reagents and a complete protocol to specifically stain glycosylated proteins (glycoproteins) that have been separated by polyacrylamide gel electrophoresis (PAGE). A gel or membrane containing separated proteins is treated with a periodate solution, which oxidizes cis-diol sugar groups in glycoproteins. The resulting aldehyde groups are detected through the formation of Schiff-base bonds with a reagent that produces magenta bands. Traditionally called the periodic acid-Schiff (PAS) reagent method, this staining technique is made easier by the convenient packaging of essential reagents in one kit with easy-to-follow instructions. The kit includes positive and negative control proteins.
To use the Glycoprotein Staining Kit, simply treat the gel or membrane containing separated proteins treated with the provided periodate-based Oxidation Reagent. This treatment oxidizes cis-diol sugar groups in glycoproteins. The resulting aldehyde groups are reacted with the Glycoprotein Stain Reagent to form Schiff-base bonds that result in the production of magenta bands of the stain. Traditionally called the periodate-acid-Schiff (PAS) reagent method, this staining technique is made easier by the convenient packaging of essential reagents in one kit with easy-to-follow instructions
