  • Patent number: 11024493
    Abstract: An analyzing device includes: a measurement data acquisition unit that acquires measurement data obtained by irradiating a plurality of irradiation positions on a sample with a laser beam and performing mass spectrometry on a sample component corresponding to each irradiation position; and an analysis unit that performs analysis of the measurement data by excluding a set of data corresponding to an excluded irradiation position among the plurality of irradiation positions each having a different irradiation portion from which a portion that has been already irradiated with the laser beam is excluded in an irradiation range irradiated when the laser beam is irradiated to each irradiation position.

  • Publication number: 20150044691
    Abstract: The present invention provides a blood marker for renal cancer, more specifically, a blood marker that can be practically used for clinical diagnosis of renal cancer. The present invention also provides a blood marker that can be practically used for follow-up after treatment such as surgery and during treatment such as medication for renal cancer. A blood marker for renal cancer selected from the group consisting of Galectin-1, Galectin-3, and ?-enolase. Galectin-1 and/or Galectin-3 as a blood marker for renal cancer for use in an examination performed before diagnostic imaging. ?-Enolase as a blood marker for renal cancer for use in monitoring during and/or after treatment for renal cancer.

  • Publication number: 20070112181
    Abstract: The present invention finds a media that can highly selectively retain proteins or peptides to be enriched/separated, as well as provides a method for selectively enriching/separating proteins or peptides using such a media. A method for enrichment/separation of a protein or a peptide, comprising separating a protein or a peptide containing an amino acid residue with a ? electron-containing group by using a media with a ? electron-containing group. Preferably, the amino acid residue is a tryptophan residue or a tryptophan residue modified with a sulfenyl compound, and the media is a media with phenyl group.

  • Publication number: 20060243899
    Abstract: The present invention provides a method which is capable of mainly detecting the objective substance by mass spectrometry and can also be applied effectively to a sample to be measured without conducting enrichment process. A mass spectrometric method comprising: in a mass spectrometry specifically ionizing a specific substance to be measured contained in a mixture sample containing the specific substance and a substance other than the specific substance by using a matrix that is more likely to ionize the specific substance than the substance other than the specific substance, to selectively measure the specific substance from the mixture. Preferably, the specific substance is a peptide modified with 2-nitrobenzenesulfenyl chloride, and the matrix is a nitrobenzene derivative such as hydroxynitrobenzoic acid. The matrix is preferably used in combination with ?-cyano-4-hydroxycinnamic acid.

  • Publication number: 20050224710
    Abstract: The present invention provides a method capable of efficiently ionizing hydrophobic peptides in MALDI-IT, MALDI-IT-TOF, and MALDI-FTICR mass spectrometers. A method of measuring a peptide with a mass spectrometer having a MALDI (Matrix Assisted Laser Desorption/Ionization) ion source, using ?-cyano-3-hydroxycinnamic acid or 3-hydroxy-4-nitrobenzoic acid as a matrix. Preferably, a peptide derivatized with 2-nitrobenzenesulfenyl chloride is measured with a MALDI-IT, MALDI-IT-TOF, or MALDI-FTICR mass spectrometer. When 3-hydroxy-4-nitrobenzoic acid is used as a matrix, the matrix is preferably used as a mixed matrix in which ?-cyano-4-hydroxycinnamic acid is combined.

  • Patent number: 3983003
    Abstract: A hyaluronic acid-enriched mycobacteria culture medium whose base is either Dubos oleic acid-albumin liquid medium or a physiological mixture of fresh yeast extract in a phosphate buffer of pH 5.5 to 7 optionally containing bovine serum albumin, glycerine, a contaminating organism-growth inhibitory antibiotic, and a gelatinizing agent to solidify the culture medium for plate use. The culture medium has particular utility for the in vitro cultivation of leprosy mycobacteria, which exhibit prolific growth when inoculated and maintained in such culture medium at temperatures within the range of about 25.degree.C to about 37.5.degree.C.
