• To overcome limitations of 2D gel electrophoresis, alternative techniques based on multidimensional liquid chromatography have been recently developed ( 1 , 2 ). (mcponline.org)
  • To answer directly the question of whether angiotensin II exists in the brain, independent of blood-borne angiotensin, and to quantify the amounts in different parts of the central nervous system, a sensitive radioimmunoassay was used to measure extracts of male adult rat brain hypothalamus and cortex after purification with high pressure liquid chromatography with a high recovery.

  • Ultra high pressure liquid chromatography (UHPLC) typically using 1.7 micron column particle size provides significantly more resolution (information) while reducing run times, and improves sensitivity for the analyses of many compound types. (gre.ac.uk)
  • The lower Ad-SoS SDS reflects reduced bone status, and the reduction was significantly more marked in those patients whose HbA 1c T was higher than 7.0% when compared with those whose HbA 1c T was lower. (springer.com)
  • Our results identify for the first time the storage locations of DMSP in microalgae, with high enrichments present in vacuoles, cytoplasm and chloroplasts. (elifesciences.org)
  • For clinical translational research, most laboratories seek high performance systems to meet their demanding needs in addition to support the connection to their mass spectrometer. (thermofisher.com)
  • With TurboFlow™ Technology, dramatically increase the return on your capital investment in mass spectrometer technology by improving data quality, lowering per-sample costs and increasing sample throughput using automated online sample preparation and multichannel liquid chromatography multiplexing.

  • Gas chromatography mass spectrometry (GC-MS) is an instrumental technique, comprising a gas chromatograph (GC) coupled to a mass spectrometer (MS), by which complex mixtures of chemicals may be separated, identified and quantified. (gre.ac.uk)
  • Therefore, the authors developed a stereoselective high performance liquid chromatography-atmospheric pressure chemical ionization mass-spectrometry assay for the quantification of the enantiomers of methadone and a d6-labeled isotopomer. (ovid.com)
  • Antibacterial assay revels Lawsonia inermis showed highest zone of inhibition on Proteus sps. (ijper.org)
  • To overcome these limitations, parallel reaction monitoring (PRM) has been developed by leveraging high-resolution Orbitrap mass analyzers to improve assay specificity because of monitoring fragment ions with parts per million (ppm) mass accuracy ( 13 , 14 ). (mcponline.org)
  • Likewise, the incorporation of high-resolution time-of-flight (TOF) mass analyzers has been used to improve the accuracy of reaction monitoring methods, including their use in data-independent approaches such as SWATH ( 15 , 16 ). (mcponline.org)
  • Due to the thermal lability of the strained cyclobutane moieties, the ladderane lipids are difficult to analyze by gas chromatography. (uu.nl)
  • Objetivo: El objetivo del presente estudio consistia en desarrollar un metodo rapido y sensitivo para la cuantificacion de resveratrol, un compuesto de tipo polifenolico con multiples propiedades beneficiosas para la salud, en plasma de raton. (thefreelibrary.com)
  • El porciento de recuperation de resveratrol en plasma de raton fue de 85 [+ or -] 10% (promedio [+ or -] desviacion estandar). (thefreelibrary.com)
  • Conclusion: El metodo que hemos desarrollado permite la cuantificacion de resveratrol en plasma de raton de manera rapida y sensitiva. (thefreelibrary.com)
  • 12%, referred to the initial concentration of COC), and its concentration was slightly higher in preserved compared with unpreserved plasma at both storage temperatures chosen. (oup.com)
  • Method: BLG was enzymatically hydrolyzed by different proteases at an enzyme-to-substrate ratio of 1:100 under HHP (100 MPa) and compared with hydrolysates obtained under atmospheric pressure (AP-EH at 0.1 MPa). (mdpi.com)
