Publication number: 20250019780Abstract: The present invention is directed to a method of determining DNA concentration in a DNA virus. The invention features three basic steps. The initial step is the specific capture of a defined amount of virus capsid particles on a first solid phase. The second step is lysis of the capsid to release the virus DNA from the first solid phase into a lysis solution. After separating the lysis solution from the first solid phase, the third step is contacting the lysis solution with a second solid phase. The second solid phase captures total DNA derived from the captured capsid. The present invention is also directed to a method for measuring the percentage of full virus capsid, comprising first determining the ssDNA concentration in viruses, and then converting the ssDNA concentration to percentage of full virus capsid using a calibration curve having DNA concentration plotted against standards of % of full capsids.Type: ApplicationFiled: September 27, 2024Publication date: January 16, 2025Inventors: Robert F. Zuk, Samuel Yang, Alex Ho Fai Lee, Indrani Chakraborty, Pu Li, Wai Choi

Patent number: 11936017Abstract: A battery pack for an electric vehicle or a hybrid vehicle may include a housing, a stack of battery cells disposed within the housing, and a cooling subassembly. The housing typically holds the cell stack together, and the cooling subassembly typically cools the cell stack to prevent damage to the battery cells and to maintain the performance of the battery cells. The cooling subassembly may include a cold plate defining a liquid flow channel and one or more thermoelectric devices (TEDs) that are operable to cool the cell stack when current is supplied thereto. Heat spreaders may be employed within the battery pack, and exemplary configurations of components to thermally and mechanically couple the cooling subassembly are described.Type: GrantFiled: November 15, 2022Date of Patent: March 19, 2024Assignee: Hyliion Inc.Inventors: David Scott Thomas, Alex Ho Yang, Timothy Hughes
