    摘要： A mass spectrometer including a sample attaching member of attaching a sample, an ionizing chamber including an introductory port of the sample attaching member and an ionization source of generating a sample ion, a vacuumed chamber having a mass analyzer of analyzing the sample ion, and an opening/closing mechanism provided between the ionizing chamber and the vacuumed chamber, in which the opening/closing mechanism is controlled from a closed state to an open state after introducing the sample attaching member into the ionizing chamber to thereby enable to perform ionization with inconsiderable fragmentation at a high sensitivity with a high throughput

    摘要： When a liquid mixture of two samples such as biological samples labeled with stable isotopes is subjected to a relative quantitative analysis using a liquid chromatography-tandem mass spectrometry system, various constituents are simultaneously ionized. Accordingly, sufficient time required for second mass spectrometry is not ensured, whereby some ions remain unanalyzed after measurement. To address this problem, after second mass spectrometry, amino acid sequencing is performed using the analysis data of the second mass spectrometry, which enables determination on the presence/absence of a specific amino acid labeled with a stable isotope. When the specific amino acid is present, the m/z value of an isotopically-labeled-paired ion in an MS spectrum is calculated, and non-target information for use in second mass spectrometry is created using the calculated m/z information. This avoids redundant second mass spectrometry on sample components derived from the same peptide while allowing second mass spectrometry to be efficiently performed.

    摘要： The selection of oocytes has largely relied on manual procedures, resulting in their lack of uniformity. Groups of oocytes are prepared and sorted, the current responses of these groups of oocytes upon exposure to lysophosphatidic acid (LPA) are measured, the response of G protein-coupled receptor (GPCR) is determined for each group of oocytes, and desirable groups of oocytes are selected on the basis of the response of GPCR. In this way, oocytes having a uniformly high response of GPCR can be selected.
