Oligosaccharide Library Immobilization Service

Oligosaccharide Library Immobilization Service

Safeguarding the Foundations of Your Research with Oligosaccharide Library Immobilization

Oligosaccharide libraries or related other molecules can be immobilized on different types of solid phase supports for use in affinity purification of oligosaccharides libraries, analysis of samples, and subsequent processing and applications. CD BioGlyco provides different oligosaccharide library immobilization services according to the client's needs.

  • We select slides as the immobilization phase and print different oligosaccharide libraries using contact printing or piezoelectric (non-contact) printing techniques.
    • We print a small amount of the oligosaccharide solution as a spot on the surface of the slide.
    • The slides are incubated, causing the oligosaccharide samples to become immobilized on the slide surface.
    • We enclose the slides to prevent non-specific binding of chemicals to the oligosaccharides. At the same time, slides containing oligosaccharide samples are covered with a specific protein buffer and incubated to cause equilibrium binding.
    • We wash the slides to remove unbound proteins and analyze them. In this process, we fluorescently label the bound proteins in advance to facilitate subsequent fluorescence detection.

  • In addition, we provide specific oligosaccharide library immobilization services that include, but are not limited to, the following:
    • Glycan coupling to N-hydroxysuccinimide (NHS)-activated glass slide
    • Glycan coupling to epoxide-activated glass slide
    • Glycolipid and lipid-derivatized glycan deposited onto nitrocellulose-coated slide
    For the former two, we utilize chemical methods to couple the free amine at the reduced end of the oligosaccharide to the slide so that it is immobilized on the slide. At the same time, we examine the slides using oligosaccharide-binding proteins after cleaning the unattached material. The assay consists of a direct fluorescence assay and a fluorescence-labeled auxiliary reagent assay.
    For the third, we use nitrocellulose microarrays to deposit oligosaccharide libraries onto nitrocellulose-coated slides in a noncovalent manner and block them appropriately to reduce nonspecific binding.


Technology: Capture and release electrospray ionization mass spectrometry (CaR-ESI-MS)

Journal: Analytical Chemistry

IF: 7.4

Published: 2017

Results: In this work, an immobilization-based CaR-ESI-MS assay is described that is simultaneously capable of screening for known concentrations of free human milk-oligosaccharide (HMO) mixtures for binding to lectins. A library of 31 free HMOs was screened against three stable mutants of the human galactoglucan lectin (hGal) protein to establish the reliability of the assay. The assay was also successful in identifying most of the HMO ligands with the highest affinity (or sets of isoforms containing the highest affinity ligands) in the libraries for each of the three hGal species. Remarkably, for each lectin, the CaR-ESI-MS screening took <1 h to complete and consumed <5 ng of each HMO and <0.5 μg of protein.
