High Resolution Screening and Quantitative Analysis of Antibiotics in Drinking Water

submitted by: Chrom Solutions

Jonathan Beck discusses online sample pre-concentration and extraction of water samples followed by analysis with high-resolution, accurate mass (HR/AM) detection, quantitation and confirmation. Screening, confirmation and quantitation of antibiotics in drinking water was done in the same analytical run with the Thermo Scientific Orbitrap platform.

Human Cell-Free Expression System Generates Stable-Isotope-Labeled Protein Standards for Mass Spec

submitted by: Chrom Solutions

John Rogers presents his scientific poster about human cell-free expression system for the production of stable-isotope-labeled (heavy) proteins using HeLa cell lysates. Six different stable-isotope-labeled proteins were produced. Isotope incorporation efficiency of greater than 95% was observed for IVT reactions.
