Glycan Mapping of Conjugated Vaccines Testing
The glycosylation profile of a conjugate vaccine is critical to its efficacy and safety. Glycan mapping, the process of characterizing the sugar moieties attached to proteins or lipids in biopharmaceuticals such as vaccines, plays a pivotal role in ensuring that these products meet stringent regulatory standards. In this service, we employ advanced analytical techniques to map glycans on conjugated vaccines, providing our clients with comprehensive data that can be used for quality assurance and product development.
Conjugate vaccines are composed of a pathogen-derived antigen linked to a carrier protein or carbohydrate via a chemical linker. The glycosylation pattern of the conjugate is essential as it can influence immune responses, stability, and toxicity. Glycan mapping allows us to identify potential variations in manufacturing processes that could affect product consistency.
Our team uses state-of-the-art mass spectrometry (MS) techniques such as high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS), which enables the precise quantification of glycan structures. Additionally, we utilize capillary electrophoresis time-of-flight mass spectrometry (CE-TOF MS) for comprehensive analysis. These methods provide detailed information about the type and distribution of glycans present in the conjugate.
The glycosylation profile can vary due to differences in manufacturing processes or batch-to-batch variability, which is why it's crucial to standardize these profiles across all batches produced by a manufacturer. Glycan mapping helps ensure that each batch meets the required specifications set forth by regulatory bodies like the World Health Organization (WHO), European Medicines Agency (EMA), and US Food and Drug Administration (FDA).
By understanding how glycosylation impacts the overall structure and function of the vaccine, researchers can optimize production methods to enhance safety and effectiveness. This service is particularly important for new vaccines where there may be limited historical data on expected glycan profiles.
In addition to characterizing individual batches, we also conduct comparative studies between different lots produced by various manufacturers or at different stages of development. Such comparisons help identify any inconsistencies that might arise during manufacturing or formulation changes and allow for timely adjustments if necessary.
Our expertise lies not only in executing these complex analyses but also in interpreting the results accurately so that our clients can leverage this information effectively within their organizations' workflows. With detailed reports tailored to meet specific client needs, we ensure transparency throughout every step of the process, from sample preparation through final analysis and reporting.
