  • Patent number: 10119967
    Abstract: The present invention provides kits and assay methods for the early detection of pathogens, precise identification of the etiologic agent, and improved disease surveillance. More specifically, the present invention discloses an immunoassay leading to the rapid and simultaneous detection of antibodies to a wide range of infectious pathogens in biological fluids of infected patients. This immunoassay involves the covalent and oriented coupling of fusion proteins comprising an AGT enzyme and a viral antigen on an identifiable solid support (e.g. fluorescent microspheres), said support being previously coated with an AGT substrate. This coupling is mediated by the irreversible reaction of the AGT enzyme on its substrate. The thus obtained antigen-coupled microspheres show enhanced capture of specific antibodies as compared to antigen-coupled microspheres produced by standard amine coupling procedures.

    Abstract: A sorbent dialysis cartridge is provided for removal of uremic toxins from dialysate wherein the sorbent cartridges can use non-enzymatic urea-binding materials in place of urease. The cartridge can have a first sorbent layer loaded with a polymerizable urea complexing agent and a second sorbent layer loaded with a crosslinker. The crosslinker can be crosslinkable with a soluble urea complex reaction product of the polymerizable urea complexing agent and urea when passing through the first sorbent layer to form a crosslinked polymeric urea complex which is attachable to the second sorbent layer. In another option, a sorbent layer can be used which has an insolubilized crosslinked polymeric urea-bindable complex attached thereto, wherein the crosslinked polymeric urea-bindable complex can be a reaction product of a crosslinker and polymerizable urea complexing agent. Methods and sorbent dialysis systems using the cartridge, and methods of making the sorbent material, are provided.
