Ion-Exchange Chromatography Protein Behavior
Scientists from Jacobs University (Bremen, Germany) used orthogonal proteomic methods to study the behavior of proteins in ion-exchange chromatography.
Scientists from Jacobs University (Bremen, Germany) used orthogonal proteomic methods to study the behavior of proteins in ion-exchange chromatography. The researchers used a tailored protocol comprising a first separation based on isoelectric focusing with Immobiline strips under native conditions and second dimension based on an SDS-polyacrylamide gel electrophoresis run. The pI values obtained with the 2D electrophoresis procedure correlated with the ion-exchange chromatographic behavior. The proteins used in the study were thaumatin and bovine serum albumin.
LCGC’s Year in Review: Highlights in Liquid Chromatography
December 20th 2024This collection of technical articles, interviews, and news pieces delves into the latest innovations in LC methods, including advance in high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), liquid chromatography–mass spectrometry (LC–MS), and multidimensional LC.
Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
