Change How You See Proteins

Complex protein structures make the development and commercialization of biologic drugs a challenging process. Traditional shortcomings of traditional analytical technologies, like circular dichroism and FTIR spectroscopy, include limited dynamic range and usability in the analysis of secondary structure. Microfluidic Modulation Spectroscopy provides a powerful alternative, producing consistently reproducible data that goes beyond that supplied by current techniques. The high performance fully automated AQS3pro system and AQS3delta analytics package allow formulation and discovery scientists to quickly and easily run samples, process data and gain insight

The AQS3pro protein spectrometer features Microfluidic Modulation Spectroscopy. It empowers biopharmaceutical scientists to see change in the proteins’ secondary structure. The instrument combines the high energy of a laser with microfluidic flow technologies. The AQS3pro measures the amide I band spectral absorbance of proteins in solution to provide increased confidence in data and decreased resources by enabling:
