COMPOSITIONS AND METHODS FOR BETA-GLUCAN IMMUNOTHERAPY

This disclosure describes, in one aspect, a composition that includes a -glucan component and an antibody component that specifically binds to the -glucan. In another aspect, this disclosure describes a method of increasing a subject's response to -glucan immunotherapy. Generally, the method includes identifying the subject as a low binder of -glucan and administering to the subject a composition that comprises a -glucan moiety conjugated to the therapeutic antibody. In some cases, the therapeutic antibody can be an anti-tumor antibody.

Virus-microbead complex and use thereof

The present invention relates to a virus-microbead complex including a microbead and a virus layer, in which linear viruses are bound individually to the surface of the microbead, and an immunoassay kit including the same. The virus-microbead complex of the present invention is characterized in that the linear viruses are bound to the surface of the microbead so that the orientations of the linear viruses are regulated using the interaction of streptavidin-biotin introduced thereon, thereby providing a significantly increased volume to surface area ratio, increasing the number of antibodies or ligands capable of binding thereto, and as a result, mediating the binding of antibodies or ligands to a unit bead with high density, which eventually leads to an increased sensitivity in immunoassays, and an application into a suspension array. Additionally, it was confirmed that cardiac troponin I (cTnI) in serum can be detected up to 20 pg/mL by introducing a self-assembled monolayer (SAM) containing PEG to remove a non-specific adsorption.

Process of conjugation and novel synthetic oligosaccharide-protein conjugates obtained thereof

The present invention relates to an improved process of conjugation to obtain synthetic oligosaccharide-protein (OS-PR) conjugates. The process of synthetic OS-PR conjugation is a rapid process providing oligosaccharide-protein conjugates which are highly immunogenic and elicit specific and homogenous immune responses. The synthetic oligosaccharide comprising of four to eight repeating units of respective monomers and at least one in-built terminal amino linker, said synthetic polysaccharide mimics natural polysaccharide obtained from gram negative bacteria such as Neisseria meningitidis serogroups A, C, Y, W, X and Haemophilus influenzae and carrier protein is obtained from gram positive bacteria such as Clostridium tetani (tetanus toxoid) or Corynebacterium diphtheriae (CRM197) or their recombinant versions. The conjugation chemistry of the said oligosaccharide-protein conjugate of the present invention is thio-ether linkage. The present invention takes complete process time in the range of 14-22 hours. The said oligosaccharide-protein conjugates are useful in production of monovalent vaccine or multivalent combination vaccines and as diagnostic tool.
