Publication number: 20230256077Abstract: The present invention relates to the production of the receptor binding domain (RBD) of the Spike glycoprotein 1 of the SARS-CoV-2 in mammalian cell expression systems, and the successive method of purification thereof. A recombinant plasmid containing the coding sequence of said RBD is produced and transfected in said mammalian cells, for example, Expi293. A high level of the protein is secreted in the medium and subsequently purified using the N-terminal tag, that can be removed by a specific protease. The present invention also includes a recombinant expression vector carrying the RBD gene, the successive methods for protein purification, the strategy for establishing a stable cell line producing the RBD, methods of use of the recombinant protein in formulating a pharmaceutical composition, including but not limited to, vaccines for preventing SARS-CoV-2 induced diseases.Type: ApplicationFiled: December 19, 2022Publication date: August 17, 2023Inventors: Alan CHANG, Fabrizio Maria ANELLA, Clement M.

Patent number: 8190275Abstract: A first home automation control device is configured to control a first electrical appliance and to communicate via a peer-to-peer network with a second home automation control device which is configured to control a second electrical appliance. When the first home automation control device discovers the presence of the second home automation control device, the first home automation control device negotiates with the second home automation control device to determine a goal. The first home automation control device and the second home automation control device then jointly execute a task to achieve the goal. The goal may be an energy savings goal.Type: GrantFiled: June 22, 2009Date of Patent: May 29, 2012Inventor: Michael Alan Chang
