Genedata Expressionist Software Solutions for MS-Based Contaminant Detection: Focus on Polysorbates
Journal of Pharmaceutical Sciences Publication
Although widely used as excipients in biotherapeutic formulations, polysorbates such as PS20 and PS80 may degrade through oxidation or hydrolysis, generating molecular species that can affect the quality, efficacy, safety, and stability of biopharmaceuticals. Consequently, identifying and characterizing polysorbate degradation is key to developing and commercializing therapeutic protein products.
By delivering information-rich data at the molecular level, mass spectrometry offers a powerful approach to overcome the challenges of analyzing these complex and heterogeneous molecules. However, evaluation of the large volumes of highly complex MS data obtained from samples containing polysorbates typically requires laborious and time-consuming expert analysis.
