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

Rheology is the science of material flow. It is also a science with a reputation for some fairly daunting mathematics. But look past these first principles and rheology has immediate relevance in formulation which is readily appreciated and easily exploited.
