Patent number: 10017740Abstract: The present invention relates to brown adipose tissue (BAT) cells derived from adult stern or progenitor cells, derived from adult white fat tissue (WAT), as well as to methods for deriving such cells.Type: GrantFiled: March 20, 2015Date of Patent: July 10, 2018Assignee: Plasticell LimitedInventors: Marina Tarunina, Yen Choo, Mylvaganam Jeyakumar, Thomas Watson, Meritxell Rosell, Lilian Hook, Diana Hernandez

Patent number: 9946834Abstract: One embodiment of the invention provides a method of processing cell culture data. The data comprises results from a large number of samples, the results being obtained by performing multiple stages of cell culture in succession on each sample. Each stage represents a cell culture treatment having a particular set of conditions, such that each sample follows a protocol specified by the identity and order of the treatments applied to the cell culture. The method includes specifying a subset of the samples that yielded a desired cell culture outcome. The method further includes performing a computer-implemented analysis of the results from the samples in the subset to produce an ordering or grouping for the results. The ordering or grouping helps to identify one or more protocols that are effective for obtaining the desired cell culture outcome. The analysis for producing the ordering or grouping utilizes information on similarities between different protocols.Type: GrantFiled: September 21, 2010Date of Patent: April 17, 2018Assignee: PLASTICELL LIMITEDInventors: Christopher Johnson, Marina Tarunina, Yen Choo, Simon Lister, Robert Merrifield

Patent number: 8617807Abstract: The invention provides a method for designing a nucleic acid binding protein of the Cys2-His2 zinc finger class capable of binding to a nucleic acid quadruplet in a target nucleic acid sequence, wherein binding to base 4 of the quadruplet by an alpha-helical zinc finger nucleic acid binding motif in the protein is determined as follows: if base 4 in the quadruplet is A, then position +6 in the alpha-helix is Glu, Asn or Val; if base 4 in the quadruplet is C, then position +6 in the alpha-helix is Ser, Thr, Val, Ala, Glu or Asn; if base 4 of the quadruplet is G, the position +6 in the alpha helix is Arg or Lys; if position 4 in the quadruplet is T, then position +6 in the alpha helix is Ser, Thr, Val or Lys.Type: GrantFiled: July 14, 2006Date of Patent: December 31, 2013Assignee: Gendaq LimitedInventors: Yen Choo, Aaron Klug, Mark Isalan
