20130029423 | METHOD OF EFFICIENTLY ESTABLISHING INDUCED PLURIPOTENT STEM CELLS - Provided are a method of improving the efficiency of establishment of iPS cells, comprising the step of contacting one or more substances selected from the group consisting of members of the GLIS family (e.g., GLIS1) and nucleic acids that encode the same and one or more substances selected from the group consisting of members of the Klf family and nucleic acids that encode the same, with a somatic cell, an iPS cell comprising an exogenous nucleic acid that encodes a member of the GLIS family or a member of the Klf family, that can be obtained by the method, and a method of producing a somatic cell by inducing the differentiation of the iPS cell. | 01-31-2013 |
20100262376 | APPARATUS, METHOD AND PROGRAM FOR ANALYZING NUCLEIC ACID BASE SEQUENCE AND BASE MODIFICATION - Provided is an apparatus by which a nucleic acid may be analyzed quickly and precisely. Specifically, provided is an apparatus for analysis of a nucleic acid including: a processing unit for creating, based on a total base composition of a nucleic acid, a plurality of base composition sets, creating a hierarchical structure in which the base composition sets are hierarchized in ascending order of a number of bases in a partial base composition at a terminal position, and further creating connection relations between each of the base composition sets, and another base composition set having, at the terminal position, a partial base composition obtained by adding one base to a partial base composition at the terminal position of each of the base composition sets; a processing unit for calculating, for each of the partial base compositions, a predicted mass value of a corresponding product ion, and imparting a weight to each of the base composition sets based on a comparison between the predicted mass value and an actual mass value of a product ion derived from the nucleic acid; and a processing unit for selecting one of base composition sets belonging to each hierarchy while following the connection relations from an outermost hierarchy in the hierarchical structure, based on a weight imparted to each of the base composition sets, to thereby determine a base sequence sequentially from a terminal base of the nucleic acid. | 10-14-2010 |
