Potency Assay for Membrane Transporter Protein-based Drugs Acting on Antioxidant, Redox, and Apoptosis Response Pathways

Description of Technology:

This technology includes a method of analyzing the potency of membrane transporter protein-based drugs acting on intracellular antioxidant and redox response pathways (and associated apoptosis pathways), wherein the drug delivery and activity is lipid associated. The present invention is a cell-based bioassay for measuring the bioactivity of drug substance and formulated drug product by determining the drug's dose-dependent inhibitory effects on 4 hydroxynonenal (4-HNE)-induced antioxidant response element (ARE) activity.

Exo-Clean Technology for Purifying Extracellular Vesicle Preparations from Contaminants

Description of Technology:

Extracellular Vesicles (EVs), including exosomes and microvesicles, are nanometer-sized membranous vesicles that can carry different types of cargos, such as proteins, nucleic acids and metabolites. EVs are produced and released by most cell types. They act as biological mediators for intercellular communication via delivery of their cargos. This unique ability spurred translational research interest for targeted delivery of therapeutic molecules to treat a wide range of diseases.

Molecular Nanotags for Detection of Single Molecules

Description of Technology:

Biological nanoparticles, like extracellular vesicles (EVs), possess unique biological characteristics making them attractive therapeutic agents, targets, or disease biomarkers. However, their use is hindered by the lack of tools available to accurately detect, sort, and analyze. Flow cytometers are used to sort and study individual cells. But, they are unable to detect and sort nanomaterials smaller than 200 nanometers with single epitope sensitivity.
