Detection of Pressure-Induced Aggregation Using MicrofluidicModulation Spectroscopy (MMS) The ability to detect protein aggregation is important at all stages of drug development. Early detection of aggregation is most desirable to inform development decisions since aggregation can negatively affect the functionality of a protein. Application Note Introduction Protein aggregation is a recognized signal of instability and … “Detection of Pressure-Induced Aggregation Using Microfluidic Modulation Spectroscopy (MMS)”

Common structural characterization methods such as FTIR and CD have known limitations in reproducibility and sensitivity which adversely increase the lowest level of quantitation (LOQ) achievable when measuring structural impurities and similarity. This application note will highlight the MMS system developed by RedShiftBio, a new protein characterization method which generates reproducible high resolution measurements. Demonstrated here, across a structural impurity range of 0–10%, are lower LOQ values compared to those possible using FTIR and CD.
