LC/MS/MS MRM Library for Metabolic Enzymes in Yeast
For LabSolutions™ LCMS Software
Includes MRM Analysis Conditions Necessary for Analyzing Metabolic Enzymes
An enormous number of MRM conditions need to be evaluated in order to analyze a large number of proteins.
This MRM library includes such analysis conditions, greatly facilitating the initial preparation for analysis. By allowing the use of proven methods, it greatly reduces the time needed for method development.
Ideal for the Analysis of Enzymes Related to Primary Metabolism Derived from Yeast
This product provides a library consisting of 3,584 MRM transitions, including stable isotopes. It covers all 498 trypsin digested peptides of 228 types of enzymes derived from budding yeast, which is used for the production of bioethanol or other materials, or as a model organism for basic research. This library enables a variety of enzyme measurements, including those related to the major metabolic pathways of glycolysis, the TCA cycle, the pentose phosphate cycle, and amino acid metabolism.
Comparative Analyses Using Stable Isotopes
The MRM analysis conditions for 13C-labeled peptides, for all MRM transitions, are listed. Using these conditions enables comparative analyses.
For example, a gene deficient yeast group grown with unlabeled glucose can be compared with a control yeast group grown with labeled glucose.
The method parameter list included in this package can be used to create methods that analyze targeted components only.
MRM Analysis of Gnd1p Trypsin Digested Peptides in Gene-Disrupted Strains
Shown below are representative chromatograms for a BY4742pfk1Δ strain (light) grown with unlabeled glucose (a), and a S288C strain (heavy) grown with 13C-labeled glucose (b). Additionally, TIC chromatograms of Gnd1p in gene-disrupted strains are shown in (c), (d), and (e). In GND1 disrupted strains, Gnd1p was not detected, whereas in PFK1 disrupted strains, large numbers of Gnd1p were detected.

News / Events
Shimadzu has released the LCMS-9050 Quadrupole Time-of-Flight Liquid Chromatograph Mass Spectrometer.
The LCMS-9050 is a quadrupole Time-of-Flight (Q-TOF) mass spectrometer system designed with technologies developed for Shimadzu LCMS series models and that results in among the highest mass accuracy stability levels available.
Dementia / Alzheimer‘s disease
Shimadzu is a leading driver in developing healthcare solutions with technology developments ranging from advanced imaging systems for use in medical diagnosis and treatment, engineering mass spectrometry-based solutions for exploring ways to discover disease biomarkers as well as building MS solutions for daily routine quantitation in biological fluids.
Anti-doping policies, rules and regulations are governed by the World Anti-Doping Agency (WADA). Doping is not only harmful to athletes who take performance-boosting drugs, but also affects the integrity of a sport. Shimadzu instruments can help ensure clean sports and here are a few applications.
Shimadzu has released the LCMS-2050 High-Performance Liquid Chromatograph Mass Spectrometer.
The LCMS-2050 single quadrupole mass spectrometer combines the user-friendliness of an LC detector with the excellent performance of MS to provide a complete package of easy to use high-level performance and compactness.
Shimadzu has released High Resolution Accurate Mass Library for Forensic Toxicology
The High Resolution Accurate Mass (HRAM) Library includes two MS/MS spectral libraries. Each library is built using two different separation conditions and is suitable for targeted or non-targeted screening of drugs of abuse, psychotropic drugs, pharmaceuticals, pesticides, and other compounds of toxicological interest.
