Let’s go back to the early 1990s when an important innovation was starting to cause a stir. Electrospray ionization (ESI) essentially allowed liquid chromatography (LC) and mass spectrometry (MS) to be combined much more easily as an analytical technique.

A concern raised by the rise in routine MRI screening within the healthcare industry is that the ability to detect abnormalities within the body may currently be running ahead of our understanding of their possible consequences, making it difficult to determine a sound course of action. Here then analytical science is arguably advancing beyond current requirements.
In this second article of a short series Dr Paul Kippax is looking at the how recent innovations are substantially enhancing the value and informational productivity of some of our established and trusted analytical techniques. This time, the addition of multiple detectors to a GPC/SEC analysis…

In this application note, we show that Malvern’s OmniSEC software can now communicate with Waters Empower® for the seamless exchange of sample sequences. A selection of proteins was used to demonstrate the measurement of protein molecular weight, oligomeric and aggregation state.
In this application note, one protein, interferon α-5, was conjugated with two different PEG molecules in different reactions. The protein and PEG molecules were characterized individually using multi-detector SEC, followed by the PEGylated conjugates. Their composition, molecular weights and intrinsic viscosities were measured. This work was performed by Celares GMBH, Germany with samples provided by DIGNA BIOTECH, Spain
