β¦ Synopsis
Recent advances in optical and spectroscopic technologies have enabled a plethora of Raman spectrometers that are suitable for studies of protein pharmaceuticals. Highly sensitive Raman spectrometers have overcome the handicap of the fundamentally weak Raman effect that hampered their applications to protein pharmaceuticals in the past. These Raman spectrometers can now routinely measure protein therapeutics at the low concentration of 1 mg/mL, which is on par with other spectroscopic methods such as CD, fluorescence and FTIR spectroscopies. In this article, various Raman techniques that can be used for protein pharmaceutical studies are reviewed. Novel Raman marker of proteins discovered from fundamental studies of protein complexes are examined along with established Raman spectra and structure correlations. Examples of Raman spectroscopic studies of protein pharmaceuticals are demonstrated. Future applications of Raman spectroscopy to protein pharmaceuticals are discussed.
