  • Patent number: 9946834
    Abstract: 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.

  • Patent number: 9574174
    Abstract: A method for determining the effect of a plurality of culture conditions on a cell, comprising the steps of: a) providing a first set of groups of cell units each comprising one or more cells, and exposing said groups to desired culture conditions; (b) pooling two or more of said groups to form at least one second pool; (c) subdividing the second pool to create a further set of groups of cell units; (d) exposing said further groups to desired culture conditions; (e) optionally, repeating steps (b)-(d) iteratively as required; and (f) optionally assessing the effect on a given cell unit of the culture conditions to which it has been exposed.

  • Patent number: 8617807
    Abstract: 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.

  • Patent number: 8318492
    Abstract: The present invention relates in one aspect to a method for determining the cell culture history of a cell unit labelled with more than one type of tag comprising the steps of: (a) measuring one or more parameters of each tag that is used to label the cell unit; (b) identifying each tag in the cell unit; and (c) correlating the identity of each tag to the identity of the cell unit and/or the specific cell culture conditions to which the cell unit has been exposed.
