CHARACTERIZATION CORNER – A New Weapon in Formulation Development
Drug Development and Delivery recently published a column about using Microfluidic Modulation Spectroscopy (MMS) to assess critical factors in the design of a biological drug substance. These include dosage form, concentration, route of administration, type of API, and type of formulation. With the requirements of formulation development of biopharmaceuticals becoming more demanding, the evolution of analytical tools that can measure stability over a wide concentration range, in the presence of complex buffer systems is critical.

Whitepapers, Application & Technical Notes
MMS For Protein Therapeutic Drug Analysis - White Paper
This whitepaper provides an overview of RedShiftBio’s Microfluidic Modulation Spectroscopy technology and the performance that can be achieved in protein characterization. Specifically the white paper presents significant increases in sensitivity and concentration range for determining protein similarity (fingerprinting), quantitation, protein secondary structure, and protein stability and aggregation through thermal and chemical denaturation methods
Microfluidic Modulation Spectroscopy (MMS) Fills an Analytical Gap with a Lower LOQ for Measuring Protein Misfolds and Structural Similarity
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.
Thermal Denaturation Analysis of Bovine Serum Albumin over Wide Concentration Range by Microfluidic Modulation Spectroscopy
In this note, MMS was used to study the heat-induced thermal denaturation of BSA. The results show replicate measurements are very reproducible (99% similarity), and that MMS provides accurate secondary structure measurements for protein samples over a wide concentration range
(1 to 100 mg/mL).
