Publication number: 20240044886Abstract: The present invention is directed to biochemical assay methods, which re-use a hapten-immobilized test probe and reagents for quantitating an analyte or measuring kinetic binding in different samples, anywhere from about 3 to 20 times, while maintaining acceptable assay performance. The methods use a conjugate solution either comprising (i) an anti-hapten antibody and a capture antibody against an analyte, or (ii) an anti-hapten antibody and streptavidin, in each cycle and regenerate the hapten-coated test probe by dipping the test probe in an acidic solution having pH about 1-4, optionally further dipping in a DMSO solution, after the completion of each cycle of reaction. The robustness of the hapten-immobilized solid phase allows utilization of denaturation reagents for efficient elution of the immune complexes after each cycle without compromising the binding activity of the hapten on the solid phase.Type: ApplicationFiled: October 7, 2020Publication date: February 8, 2024Inventors: Robert F. ZUK, Pu LI, Jackie Shek Kei CHAN, Indrani CHAKRABORTY

Patent number: 8435094Abstract: A modular toy vehicle design having a universal mating system between the body of the vehicle and the chassis such that multiple body styles will interchangeably mate with multiple chassis designs and where electrical interfaces are automatically established between the body and the chassis simply by mating and aligning the two together. The design allows for an electrical connection to be made in the process of mechanically mating and aligning the body of a toy vehicle to its chassis thereby powering electronic features that are physically connected to the body with the power source which is housed in the chassis. When the body is properly aligned and mounted, the electrical interfaces are automatically established. There is no separate step of plugging together mating connectors where one connector extends from a wire bundle electrically interfacing with the body and the mating connector extends from a separate wire bundle electrically interfacing with the chassis.Type: GrantFiled: February 15, 2011Date of Patent: May 7, 2013Assignee: Ridemakerz, LLCInventors: Donald W.
