GlycoLink Immobilization Kits and Resin


Hydrazide-activated resin to immobilize glycoproteins for affinity purification.

GlycoLink Immobilization Kits

Thermo Scientific GlycoLink Immobilization Kits provide affinity columns and reagents to immobilize glycoproteins through oxidized sugar groups for use in affinity-purification applications or studies of protein-protein interactions.

The GlycoLink Kits use hydrazide-activated resin and a special catalyst to prepare affinity columns with polyclonal antibodies, which typically have abundant carbohydrates (glycosylation) on their Fc portions. Any glycosylated proteins (even monoclonal antibodies) that contain periodate-oxidizable carbohydrate groups can be immobilized with these kits to make reusable affinity columns. Antibodies immobilized by this hydrazide immobilization chemistry have unobstructed antigen-binding sites and optimal purification capability. Prepared columns with stable glycoproteins or antibodies can be regenerated and reused at least five times for affinity-purification without significant loss in binding capacity.

Highlights:

  • High-capacity – immobilize 1 to 10mg of oxidized antibody or other glycoprotein per milliliter of resin
  • Fast and efficient – immobilize in as few as 30 minutes; achieve at least 90% coupling of most glycoproteins in less than 4 hours (efficiency depends on the amount and type of glycosylation)
  • Specific immobilization – the hydrazide-activated UltraLink Resin conjugates only to purified glycoproteins whose sugar (e.g., sialic acid) groups have been gently oxidized with periodate
  • Stable attachment – resonance structure of the hydrazone bonds are sufficiently stable for multiple affinity purifications with one batch of prepared resin; no stabilization step is required
  • Preserves antibody function – immobilizes IgG via the Fc region, thereby keeping both antigen binding sites available for capturing target
  • Convenient sizes – choose from two complete 10-column kits: one with 1mL columns and one with 0.1mL columns

Applications:

  • Purify antigens using covalently coupled antibodies
  • Determine binding partners for a glycoprotein of interest
  • Perform large-scale affinity purifications

Includes:

Kits contain GlycoLink Columns; coupling buffer, coupling catalyst and wash buffer; oxidizing reagent; desalting columns, PBS buffer pack; and column accessories

General structure and reaction scheme for the Thermo Scientific GlycoLink Immobilization for immobilization of protein at carbohydrates.
Chemistry of glycoprotein immobilization with Thermo Scientific GlycoLink Resin. Glycoproteins with oxidized sugars contain aldehyde groups which will conjugate to the hydrazide-activated beaded resin support. Learn more about carbonyl-reactive immobilization methods and about hydrazide crosslinking chemistry.

The GlycoLink Immobilization Kit method is especially useful for glycoproteins, such as polyclonal antibodies, because it can allow molecules to be attachmed at a domain that will not interfere with active binding sites that are critical for the intended affinity purification. Carbohydrate moieties in glycoproteins contain common sugars with cis-diol groups that are easily oxidized with sodium meta-periodate to yield aldehydes. When incubated with hydrazide resin, these aldehyde groups react with the hydrazide groups on the resin to form stable, covalent bonds. This reaction is enhanced by the Thermo Scientific GlycoLink Coupling Catalyst, increasing coupling efficiency and decreasing incubation times. The entire coupling reaction occurs in 2 to 4 hours in a simple non-amine buffer containing the catalyst. Coupling efficiencies with antibodies and typical glycoproteins are generally greater than 85%, resulting in 1 to 10mg of immobilized protein per milliliter of Thermo Scientific UltraLink Hydrazide Resin.

General glycoprotein coupling efficiencies. For each experiment, 0.4mg of protein was immobilized on 0.1mL of Thermo Scientific GlycoLink Immobilization Resin (hydrazide-activated UltraLink Resin).
