  • Publication number: 20130045500
    Abstract: The present invention provides a method of figuring out an effect of a medicine exerting on the same cell quantitatively over a time. A cell evaluation method includes a step of culturing cells on a cell-culture base material that is capable of culturing spheroids, and a step of measuring a change over a time in the number of the spheroids formed through the former step or a percentage of the spheroids formed through the former step relative to an entire cultured cell.

  • Publication number: 20120040452
    Abstract: It is an object of the present invention to identify a glypican-3-derived peptide which can bind to HLA-A2 and activate human killer T cells, so as to provide a means for carrying out an immunotherapy which is able to target approximately 40% of Japanese patients suffering from several types of cancers, which express GPC3 at a high level. The present invention provides a peptide of any of the following (A) or (B): (A) a peptide, which has the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3; or (B) a peptide, which has an amino acid sequence comprising a substitution or addition of one or two amino acids with respect to the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3, and which has ability to induce killer T cells.
