A new infrared spectroscopy technique, microfluidic modulation spectroscopy (MMS), delivers reproducible protein characterization over close to four orders of magnitude in protein concentration (from 0.1 to 200 mg/mL). This technique characterizes samples from the earliest stages of development through to manufacture.

This article introduces a new infrared (IR) technique, microfluidic modulation spectroscopy (MMS), that is designed to address these needs, and presents data from measurements of commercially available proteins. The data demonstrate significant increases in sensitivity, dynamic range, and utility for the determination of protein similarity (fingerprinting), quantitation, protein secondary structure, and protein stability and aggregation through thermal and chemical denaturation methods.
