Bioconjugation Specialties: Anti-Ig dextran conjugates Reference: J. Immunol. 157: 2229 (1996); C. M. Snapper and J. J. Mond. A model for induction of T cell-independent humoral immunity in response to polysaccharide antigens' Protein-carbohydrate conjugates for conjugate vaccines Reference: Vaccine 2006 24:716-29. Peptide conjugates to enhance binding and detection for ELISAs Amino-dextran, size fractionated (Am dex). Amino dextran prepared according to Inman JK. J Immunol. 114:704-9, 1975 is size fractionated to provide a more homogeneous product. Other Bioconjugation Services Include: Antibody and protein biotinylation and fluorescent labeling Antibody-enzyme conjugates and other protein-protein linkages Conjugations for peptide immunogens and vaccines Conjugations with hydrophobic peptides. Pegylation Conjugate Vaccines. We have decades of experience in conjugate vaccines and proprietary chemistry for preparing carbohydrate conjugate vaccines. One of our inventions licensed by GlaxoSmithKline underlies the chemistry of their pediatric conjugate vaccines Menitorix, Nimenrix and Synflorix. Protein Conjugate Vaccine Patent Consulting. Protein conjugate vaccine patents constitute a vast body of prior art. We can help conjugate vaccine makers determine what is an innovation and what is not.
