  • Publication number: 20090280533
    Abstract: The present invention provides a cell culture medium formulation that supports the in vitro cultivation, particularly in suspension, of mammalian cells, particularly epithelial cells and fibroblast cells, and methods for cultivating mammalian cells in suspension in vitro using these media. The media comprise a basal medium and a polyanionic or polyanionic compound, preferably a polysulfonated or polysulfated compound, and more preferably dextran sulfate. The present invention also provides chemically defined, protein-free eukaryotic cell culture media comprising an iron chelate and zinc, which is capable of supporting the growth (and particularly the high-density growth of mammalian cells) in suspension culture, increasing the level of expression of recombinant protein in cultured cells, and/or increasing virus production in cultured cells.

  • Publication number: 20080286868
    Abstract: The present invention is directed generally to metal binding compounds which may be added to cell culture media to replace factors required for cultivation of the cells (e.g. transferrin) which are of animal or human origin. More specifically, the invention is directed to metal binding compounds or complexes thereof comprising one or more transition element cations (such as ferrous or ferric ions), which are added to cell and tissue culture medium compositions. The metal binding compounds may be added to the media alone or may be first complexed with a transition metal ion. The invention is also directed to methods of use of such compositions, including, for example, methods for the cultivation of eukaryotic cells, particularly animal cells, in vitro. The invention also relates to compositions comprising such culture media and one or more cells, and to kits comprising one or more of the above-described compositions.

  • Publication number: 20080270456
    Abstract: A computer-based method represents a subset of a dataset table of rows and columns. The method includes selecting a set of blocking variables corresponding to blocking columns of the dataset table. For each row in the dataset table, a tuple of values for the blocking columns uniquely identifies the row within the dataset table. The method also includes selecting a set of non-blocking variables that correspond to columns of the subset. The set of non-blocking variables does not intersect the set of blocking variables. The method also includes creating a block information structure that includes both the set of non-blocking variables and, for each blocking variable in the set of blocking variables, a set of values.

  • Publication number: 20080189221
    Abstract: The invention comprises a system and method for hedging or mitigating mortality exposure risk in a portfolio of mortality-dependent instruments. A mortality risk or longevity risk of the portfolio is calculated or otherwise determined. Then the sensitivity of the portfolio to mortality risk or longevity risk is calculated or otherwise determined, in other words, how much is cost or value of the portfolio affected by a change in mortality rate. To account for that mortality exposure, a selection is made of building block mortality derivatives that include age-based mortality derivatives. The selected plurality of building block mortality derivatives are used to create a hedge against the mortality risk or longevity risk of the portfolio.

  • Patent number: 7125660
    Abstract: Methods for engineering a nucleic acid sensor molecule are provided. Biosensors comprise a plurality of nucleic acid sensor molecules labeled with a first signaling moiety and a second signaling moiety. The nucleic acid sensor molecules recognizes target molecules which do not naturally bind to DNA. Binding of a target molecule to the sensor molecules triggers a change in the proximity of the signaling moieties which leads to a change in the optical properties of the nucleic acid sensor molecules on the biosensor. Reagents and systems for performing the method are also provided. The method is useful in diagnostic applications and drug optimization.
