Abstract:
The present invention relates to an apparatus for visualizing or analyzing gene expression patterns of a biological sample using gene ontology tree and a method of the same, more precisely, an apparatus for visualizing or analyzing gene expression patterns which are regarded as biologically important using gene ontology tree by calculating complexity and a method of the same. This apparatus of the present invention is useful for comparing gene expression patterns in different biological samples using data produced by the said apparatus and the method of the present invention. According to the present invention, gene expression patterns in relation to molecular functions, biological processes or cellular components can be analyzed by investigating protein or RNA expression in biological samples. So, the apparatus and the method of the present invention can be effectively used for analysis of biologically important aspects such as functional changes, evolutionary stages or developmental stages of each biological sample.
Abstract:
The present invention relates to a method of analyzing protein modification. The method of invention for analyzing protein distribution and characteristics on one-dimensional gel provides the way to analyze proteins of samples on one-dimensional gel quantitatively and provides information on interactions among proteins and further can be effectively used for the development of a novel diagnostic and therapeutic method for a disease by screening a disease marker protein.
Abstract:
The present invention relates to a more efficient and accurate method for the identification and quantification of comparatively low abundant glycopeptides, compared with general peptides, using mass spectrum obtained by using high resolution mass spectrometer. Therefore, the method of the present invention can be effectively used for the techniques for identification of biotherapeutics and diagnosis of cancer or disease by screening glycopeptide, the disease marker (Biomarker), from various samples.
