摘要:
It is intended to provide a method of analyzing gene expression, a novel use of a receptor protein, etc. More specifically speaking, a method of analyzing gene expression characterized by comprising qualitatively analyzing the individual expression doses of a plural number of genes and thus identifying a gene showing characteristic promotion or inhibition in its expression in specific cells or tissue; a quantification kit to be used in this method; and so on. Moreover, a method of screening a compound or its salt capable of changing the binding properties of a receptor protein, which is a novel G protein-coupled receptor protein having an amino acid sequence being identical or substantially identical with the amino acid sequence represented by SEQ ID NO:9, or its salt to ligands characterized by using the above protein or its salt and a protein (for example, a lectin) showing an affinity for a sugar chain which is one of the ligands is provided.
摘要:
It is intended to provide a method of quantifying a nucleic acid and a kit for quantifying a nucleic acid. More specifically, it is intended to provide a standard comprising a synthetic polynucleotide obtained by chemical synthesis which is to be used for forming a calibration curve employed for quantifying a specific target nucleic acid in a sample, a quantification method and a quantification kit using the same, a method of diagnosing a specific disease, etc. The standard is a synthetic polynucleotide obtained by chemical synthesis. Compared with the existing standards comprising biosynthesized polynucleotides, it has an advantage that a target sequence can be precisely obtained by a convenient method. Moreover, the above-described standard suffers from little biological contamination. Therefore, it is highly safe to the environment and factors disturbing highly precise quantification can be lessened therein.
