Analytical Development

Our sophisticated analytical development module leverages extensive expertise in designing and implementing methodologies to characterise the drug substance and impurities, whilst ensuring process quality at every stage. All analytical methods are qualified according to ICH guidelines to ensure they are fit-for-purpose, and can be seamlessly transitioned into a GLP/GMP compliant environment.

Product Characterisation and Release Assays

Our comprehensive product characterisation and release assays are supported by both our in-house specialists and a network of trusted partners. These services cover the development, qualification, and implementation of analytical methods essential for assessing product quality across several parameters.

Our services include:

  • Quantity: measured using A280, BCA, ELISA, HPLC and LC-MS.
  • Purity: ensured through SDS-PAGE, HPLC, CEDEX bioanalyser, host cell protein (HCP), host cell DNA (HCDNA), bioburden, and endotoxin contamination assays.
  • Identity: HPLC, QTOF-MS, Western blot, and dynamic light scattering (DLS).
  • Potency: assessed using ELISA, and custom-designed assays.
  • Stability: R&D stability assessment to evaluate shelf life and performance including: Accelerated stability, Stress stability (forced degradation) and In-use stability.

In-process Controls and Monitoring (IPC/IPM)

We develop IPC/IPM to monitor and ensure both process and product quality, achieving batch-to-batch reproducibility. Our comprehensive IPC/IPMs are designed to monitor critical process parameters (CPPs) essential for achieving the product's critical quality attributes (CQAs). This approach enables real-time adjustments to prevent costly batch failures and supports detailed documentation in line with regulatory standards and expectations.

Our IPC/IPMs can be developed to suit your process requirements, and include:

  • Process monitoring: pH monitoring and control, dissolved oxygen (DO) levels, temperature control, agitation rate, nutrient feeding, foam control, and off-gas analysis.
  • Metabolite monitoring: tracking of feedstocks and metabolites including by-products, such as organic acids, to measure inhibitory effects on cell growth/product quality and develop control strategies.
  • Biomass monitoring: using optical density, dry cell weight, and wet cell weight measurements to assess cell growth.
  • Product concentration and yield: analysis via SDS-PAGE, Western blot, and ELISA to confirm product presence and concentration.
  • Contamination monitoring: routine checks to ensure microbial or cell line purity.
  • Process residual clearance: Endotoxin, host cell protein (HCP), host cell DNA (HCDNA), Nuclease and Protease levels, Mycoplasma, antibiotics, and other process residuals. Our analytical capabilities allow for non-standard residuals to be monitored.
