Abstract: A support for a multiplex binding experiment is functionalized with at least two different polypeptides. The polypeptides are provided in a reaction mixture along with their cognate binding partners. The polypeptides have high affinity for their cognate binding partners provided in the reaction mixture. The polypeptides and their cognate binding partners can be used in immunoassays.

Abstract: Compositions and methods comprising high affinity monoclonal antibody conjugates against several DC receptors are described herein. The inventors prepared fusion proteins with antigens for DC-targeting vaccine generation by conjugating several M. tuberculosis protein antigens with high affinity monoclonal antibodies against several DC receptors with a view to developing novel human vaccines based on in vivo DC-targeting. The findings of studies described herein indicate that vaccines bearing TB antigens can recall a potent memory antigen-specific T cell response in vitro resulting in IFN? secretion.
