DryLab and Empower: a successful combination for the optimisation of mAb subunit analysis
The development of liquid chromatography (LC) methods has long been done using a trial-and-error approach, also known as “one factor at a time” (OFAT). While this approach is the easiest to implement, it is both time-consuming and quite inefficient.
Fast and accurate absolute quantification of antibodies and antibody-drug conjugate using Isotope Dilution-Triple Quadrupole ICP-MS
Traditional “absolute” methods of analysis for protein quantification include colorimetry, amino acid (AA) analysis and UV-Vis spectroscopy but each of these techniques has its limitations.
Webinars
The production of monoclonal antibodies (mAbs) is a lengthy and complex process. It is, however, important to follow the mAb during
During this live webinar, we will outline the different analytical workflows that can be used for charge variant analysis (ion-exchange chromatography with salt or pH gradients, MS-compatible approaches, 2D-LC/MS, and icIEF) and present several case studies.
