Analyzing Host Cell Proteins Using Off-Line Two-Dimensional Liquid Chromatography–Mass Spectrometry

With the top-selling mAbs evolving out of patent there has been a growing interest in the development of biosimilars. In demonstrating comparability to the originator product, biosimilar developers are confronted with an enormous analytical challenge. This article presents a selection of state-of-the-art analytical tools for mAb characterisation and comparability assessment.

This article highlights some selected examples of the power of liquid chromatography combined with mass spectrometry (LC–MS) in the development of protein biopharmaceuticals.

Part one focusses on ways of reducing and replacing solvents commonly used as mobile phases
