2-AB-plus Labeling Kit

SKU: GKK-804 Categories: , Tags: ,


  • Convenient fluorescent labeling of glycans with 2-AB (2-aminobenzamide) by reductive amination.
  • Any purified glycan or glycan pool with a free reducing sugar may be labeled.
  • The 2-AB-plus Labeling Kit improves on the traditional 2-AB Labeling Kit (p/n GKK-404) by providing the 2-AB and Reductant already in solution.
  • You can now use what you need, and store the rest of the kit for later use, with no glass ampoules.
  • GKK-804 can be used as a direct replacement for GKK-404: when mixed, the GKK-804 2-AB labeling solution will be the same as what is made when all components of GKK-404 are combined.
  • Up to 48 samples may be processed.
