Latest Patents

One of his latest patents is related to an agglutination assay. This invention pertains to agglutination assays and associated kits, reagents, and devices. It particularly addresses methods of assaying small analytes that have few epitopes. The invention utilizes hub moieties to which multiple analytes can bind via a first epitope, along with a further moiety that can bind a second analyte epitope and is also capable of binding to a detectable particle. This results in the formation of stable agglutinated complexes, which can serve as the basis for various assay formats. Another significant patent is a modified form of saturation assay. This invention measures a free or unbound labeled reagent fraction, leading to an increase in signal presence of analyte. It employs trapping zones to concentrate the unbound or free labeled fraction, thereby avoiding loss of sensitivity. Preferably, this assay is designed as a membrane assay.
