Publication number: 20230035606Abstract: This invention provides mass spectrometry (MS) compatible nanomaterials for the selective capture and enrichment of low abundance proteins as well as MS analysis of different proteoforms of proteins, particularly cardiac proteins and different proteoforms of cardiac troponin I (cTnI) arising from post-translational modifications and sequence variations. The surface of superparamagnetic nanoparticles is functionalized with probe molecules that specifically bind to the desired protein. In an embodiment, the nanoparticles are functionalized with probe molecules having high affinity and selectivity for cTnI within the human cardiac troponin complex. This allows for MS-analysis and characterization of cTnI proteoforms from human heart tissue lysates and human blood or serum samples, and provides an accurate assay for detection of cTnI with molecular details.Type: ApplicationFiled: December 18, 2020Publication date: February 2, 2023Applicant: Wisconsin Alumni Research FoundationInventors: Ying GE, Song JIN, Timothy-Neil T.

Patent number: 5097627Abstract: Plants are hydroponically grown in a cellular water table provided with divergent grow lines along which plants are moved in plant holders. The grow lines are arranged to provide spacing between adajcent rows of plants as plants mature. Within each grow line is a variable pitch screw arrangement which provides for increased spacing between adjacent plants in a grow line as the plants mature. Four-way spacing is provided for both the leaves of the plants and their roots as the plants are suspended over the cellular water table. Maintenance of the system is facilitated by a crawl space beneath the water table which allows access to removable bottom panels of the individual cells within the water table. Plants are cultivated and serviced from the top by a man carrier system. CO.sub.2 enriched air and/or pesticides are supplied directly to the undersides of the plants by a conduit system provided within each grow line.Type: GrantFiled: February 5, 1990Date of Patent: March 24, 1992Assignee: Gourmet Gardens CorporationInventor: David S.
