Thermo Scientific™ GlycoLink IP Kit provides components for effective immunoprecipitation (IP and co-IP) based on small-scale, covalent, affinity-resin immobilisation of antibodies and other glycoproteins via oxidised sugar groups.

  • Efficient immobilisation, couple 2 to 10 µg of oxidised antibody or other glycoprotein to 20 µl of resin in 2 hours or less
  • Resonance structure of the hydrazone bonds are sufficiently stable so the antibody remains coupled during elution
  • Immobilises IgG via the Fc region, thereby keeping both antigen binding sites available for capturing target
  • Immobilise any molecule that contains oxidisable sugars, including glycoproteins for use in purifying protein interaction binding partners

This kit uses hydrazide-activated UltraLink Resin to immobilise and perform 25 IP or Co-IP assays with different antibodies or glycoprotein ligands. The method is ideal for polyclonal antibodies, which typically have abundant carbohydrates (glycosylation) on their Fc portions. Monoclonal antibodies that contain adequate carbohydrates are also effective. Antibodies immobilised by this hydrazide-to-carbohydrate method have unobstructed antigen-binding sites and optimal purification capability. The prepared glycoprotein or antibody columns can be regenerated and reused at least five times for immunoprecipitation, co-immunoprecipitation or pull-down affinity-purification without significant loss in binding capacity.

Immunoprecipitation followed by electrophoresis and excision of the protein for mass spectrometry or sequencing. Immunoprecipitation and SDS-PAGE analysis of a protein with a molecular weight similar to the antibody's heavy or light chain. Co-immunoprecipitation for determining protein-protein interactions. The kt method results in covalent attachment of oxidized sugar groups of an IP antibody (or any other glycoprotein with oxidizable carbohydrate groups) to the hydrazide resin. The antibody resin is then incubated with the sample that contains the protein antigen of interest, allowing the antibody-antigen complex to form. After washing to remove non-bound components of the sample, the antigen is recovered by dissociation from the antibody with elution buffer supplied in the kit. The entire procedure is performed in a microcentrifuge spin cup, allowing solutions to be fully separated from the resin with a brief centrifugation. Only the antigen is eluted by the procedure, enabling it to be identified and further analyzed without interference from antibody fragments.

This kit contains resin, buffers and reagents for immobilisation; desalting columns; IP lysis/wash and elution buffers for immunoprecipitation; microcentrifuge spin columns and collection tubes; and loading buffer for SDS-PAGE.
