Product information

  • Function

    BnGalNAc is a decoy substrate for the biosynthesis of O-linked glycans based on O-GalNAc. It can be used to inhibit the biosynthesis of membrane linked O-GalNAc containing glycans. Instead cells produce and excrete glycans attached to the BnGalNAc decoy substrate which can be analyzed with mass spectrometry. A more cell permeable and potent derivative of BnGalNAc called P-BnGalNAc is also available here.1

  • Mode of action

    O-linked glycans based on α-O-GalNAc residues starts with the addition of α-O-GalNAc residues to serine or threonine side chains. Next, additional sugars are added to the α-O-GalNAc residue. BnGalNAc is a cell permeable derivative of GalNAc. It enters cells and acts as a decoy substrate. Instead of adding monosaccharides to α-O-GalNAc glycoproteins, these residues are added to BnGalNAc. The corresponding glycoconjugates are excreted into the cell medium and the synthesis of mucins and other glycoconjugates based on α-O-GalNAc is inhibited.

  • Applications

    BnGalNAc has been used to study the role of mucins in colorectal cancers.23

  • Handling

    Handling instructions:
    BnGalNAc is soluble in water and PBS and added to cells in from a stock solution. Good priming/inhibition is achieved at 1mM concentration.
