  • Patent number: 11506671
    Abstract: Disclosed is a novel means for accurate qualitative and quantitative analyses for each N-glycosylation site. The method of analyzing N-linked sugar chain(s) of glycoprotein according to the present invention comprises: treating a part of a glycopeptide-containing sample to be analyzed with endo-?-N-acetylglucosaminidases to cleave off sugar chains while leaving one GlcNAc of the chitobiose core on the Asn at the N-glycosylation site; subjecting the obtained sugar chain-cleaved sample to preliminary liquid chromatography/mass spectrometry; predicting the retention time of the glycopeptide of interest and the mass-to-charge ratio (m/z) of the precursor ion in main analysis based on the results of the preliminary liquid chromatography/mass spectrometry; and carrying out the main analysis. By this method, the binding sites and structures of N-linked sugar chains in a glycoprotein can be analyzed.

  • Patent number: 10520479
    Abstract: In a liquid chromatograph mass spectrometer (LC/MS) for performing mass spectrometry of fractionated samples prepared with a multi-dimensional LC or similar LC with high separatory capability, fractionated sample useful information which shows the degree of usefulness of various substances with respect to retention time is prepared from prior information which includes, for example, elution characteristics in the LC depending on the kind of column or other factors or the degree of ease of ionization in the MS. During a measurement, the preparative separation of an eluate and the preparation of fractionated samples are not performed within a period of time which has been judged to be useless based on the fractionated sample useful information. By selecting fractionated samples at each dimension of the multi-dimensional LC, the number of fractionated samples to be eventually subjected to mass spectrometry can be significantly reduced.

  • Patent number: 9588125
    Abstract: A peptide is cleaved at various bonding sites into oligopeptides or similar fragments by digestion using proteinase K (S3). The obtained fragments are separated according to their kinds by reversed-phase chromatography and fractionated (S4), and each fragment is subjected to mass spectrometry to determine its mass (S6). For each peptide fragment, an amino-acid composition is calculated from the measured mass, and amino-acid sequence candidates are deduced from that composition. The amino-acid sequence candidates of the other peptide fragments are searched for a fragment having an overlapping portion available for combining two peptide fragments to obtain amino-acid sequence candidates of the original peptide (S7). The masses of the amino-acid sequence candidates are compared with a measured mass derived from a result of mass spectrometry of the original peptide to select a correct sequence (S6 and S8).

  • Publication number: 20150256048
    Abstract: An opening/closing body operation device for operating an opening/closing body, which swings up and down, so as to open and close, has a driving unit, a slider which is moved up and down by the driving force from the driving unit and is linked to the opening/closing body and a guide member having the slider slidably disposed in the interior. The slider includes a main slider body, a sliding member that slides on the guide member, and an elastic member between the main slider body and the sliding member to support the load applied to the slider when the opening/closing body is opened or closed. The slider has a deformation allowance space for allowing elastic deformation of the elastic member caused when the slider is pressed into the guide member. Thus, the load applied to the slider to open or close the opening/closing body is reliably supported.
