The Sialidase Testing Panel contains a mixture of α2-3, α2-6, and α2-8 sialylated oligosaccharides labelled with either 2-AB or procainamide. They were developed as a process control for sialidase digestions. Applied alongside the samples, it demonstratesshows that the enzymes have the expected specificity.

*New Product (size: 20 pmol)

Sialidase Testing Panel includes a mixture of five glycans:

  1. 3′-Sialyl Lewis X [Neu5Ac-a2-3Gal-b1-4(Fuc-a1-3)GlcNAc] – contains α2-3 linked sialic acid along with branched α1-3 fucose (introducing steric hindrance for some enzymatic reactions)
  2. Sialyllacto-N-tetraose a [Neu5Ac-α2-3Gal-β1-3GlcNAc-β1-3Gal-β1-4Glc] – linear oligosaccharide containing α2-3 sialic acid attached to galactose
  3. Disialyllactose [Neu5Ac-a2-8NeuAc-a2-3Gal-b1-4Glc] – linear oligosaccharide containing α2-8 linked sialic acid
  4. Sialyllacto-N-tetraose c [Neu5Ac-a2-6Gal-b1-4GlcNAc-b1-3Gal-b1-4Glc] – linear oligosaccharide containing α2-6 sialic acid attached to galactose
  5. Disialyllacto-N-tetraose [Neu5Ac-a2-3Gal-b1-3(Neu5Ac-a2-6)GlcNAc-b1-3Gal-b1-4Glc] – branched sialic acid oligosaccharide

Purity: 89% pure as assessed by UHPLC.

Storage : Store at -20°C both before and after dissolution. This product is stable for at least 5 years as supplied.

Shipping: The product can be shipped at ambient when dry. After dissolution, ship on dry ice.

Handling: Allow the unopened vial to reach ambient temperature. Centrifuge to ensure that most of the lyophilized material is at the bottom of the vial. Add the desired volume of reconstitution medium, re-cap and mix thoroughly to bring all the oligosaccharide into solution. Ensure that any glass, plasticware or solvents used are free of glycosidases and environmental carbohydrates.
Example use Sialidase Testing Panel can be used as process positive control for sialidase digestions. Applied alongside the samples, it enables to test if the sialidase used has required specificity and if it had worked correctly.
