USP Glycosylation Profiling by HPLC
Understanding the complexity of glycosylation in biopharmaceuticals and biosimilars is crucial for ensuring product quality, safety, and efficacy. USP Glycosylation Profiling by High-Performance Liquid Chromatography (HPLC) provides a robust analytical tool to assess the structural diversity of carbohydrates attached to proteins in these biologics.
Glycosylation plays a pivotal role in the function and stability of therapeutic proteins, influencing their pharmacokinetics, immunogenicity, and overall therapeutic potential. The USP chapter on Glycosylation Profiling (USP 1869) outlines methods to characterize glycoforms by analyzing carbohydrate structures using HPLC technology.
Our service employs advanced instrumentation such as a Waters UPLC system paired with a refractive index detector (RID) or mass spectrometry (MS) for comprehensive glycan analysis. This approach ensures that we can provide detailed profiles of the various glycans present in your biopharmaceuticals and biosimilars, adhering strictly to USP guidelines.
The process begins with thorough sample preparation, where purified protein samples are subjected to digestion using enzymes like PNGase F or Endo H to release terminal sugars. These digestions are followed by derivatization steps necessary for detection by HPLC. The resulting glycans are then separated and quantified based on their retention times.
The data obtained from this process is analyzed meticulously, ensuring that the profiles align with USP specifications and industry best practices. This analysis helps in identifying potential issues related to glycosylation, such as non-compliant glycans or unusual patterns that could impact product performance.
Our service not only meets but exceeds the requirements set by regulatory bodies like the FDA and EMA, ensuring compliance with current Good Manufacturing Practices (cGMP) and quality standards. By leveraging USP Glycosylation Profiling by HPLC, you can gain valuable insights into your biopharmaceuticals and biosimilars that are critical for development, manufacturing, and quality assurance.
