Abstract: The subject invention relates to the cloning, expression and isolation of recombinant forms of beta-amyloid protein containing a N-terminal methionine (or one or more amino acids) as well as to methods of using this recombinant protein in the production of therapeutic antibodies, in the identification of therapeutic small molecules, and in the performance of diagnostic assays.

Abstract: The disclosure provides methods of detecting autoantibodies (AAs) in biological samples. The methods use capture probes that can bind to an disease-associated antigen/AA complex and a detection probe that can bind to the AAs. The presence, absence, and/or amount of the complex may be measured, wherein the presence of the complex may be diagnostic or prognostic of a disease or medical condition. The disclosure also provides methods of simultaneously detecting AAs and antigens in biological samples. The presence, absence, and/or amount of AAs and antigens may be measured, wherein the amount of antigen present and/or the amount of autoantibody present may be diagnostic or prognostic of a particular disease or medical condition.

Abstract: The invention provides stable bioconjugate-nanoparticle probes which are useful for detecting nucleic acids and other target analytes, e.g., proteins, and methods of preparing those probes.

Abstract: The invention provides methods and apparatus to assess cardiac risk and ischemia by detecting or analyzing cardiac troponin levels. Also provided are methods to detect low levels of cardiac troponin in physiological fluid samples.

Abstract: The subject invention relates to the cloning, expression and isolation of recombinant forms of beta-amyloid protein containing a N-terminal methionine (or one or more amino acids) as well as to methods of using this recombinant protein in the production of therapeutic antibodies, in the identification of therapeutic small molecules, and in the performance of diagnostic assays.

Abstract: Centrifugation is used to induce and/or enhance binding between macromolecular targets and either small-molecule ligands or larger biomolecules as single entities or mixtures. With the enhanced binding, the method of the invention permits detection of ligands that bind to target substances and improve the design of ligands. The process relies on centrifugal force to establish a differential and selective concentration gradient between macromolecular therapeutic targets and the desired ligands. Once formed, the information about the self-sorting binding events is derived by analyzing the differential gradient of macromolecules and ligands in situ or by fractionating the gradient into individual samples for independent analysis. A variety of methods or combinations thereof, can be used to look for enhanced levels of bound ligands.
