Macromolecule Developability Analysis and Method Development

Macromolecular drugs, such as monoclonal antibodies, fusion proteins, and nucleic acid drugs, are rapidly becoming the centerpiece of modern biopharmaceuticals. However, these complex biomolecules face a number of challenges during their development, from their biophysical and chemical stability to their biological activity and immunogenicity.

To ensure that these biopharmaceuticals make it to clinical development and the marketplace, Protheragen-ING Lab provides comprehensive exploitability analysis and method development services to help clients overcome these challenges and advance large molecule drugs from R&D to commercialization.

Protheragen-ING Lab's developability analysis services

Exploitability analyses are a critical step in evaluating the risks and issues that a biological drug may face during the development process. These analyses help determine the chemical and physical properties of a drug, predict its stability in storage, transport and use, and evaluate its behavior in biological systems.

Our exploitable analytical services include, but are not limited to, the following:

• Physicochemical property assessment: including solubility, pH stability, thermal stability, aggregation tendency, etc.
• Structural analysis: molecular structure characterization using techniques such as high-resolution mass spectrometry, nuclear magnetic resonance (NMR), and X-ray crystallography.
• Stability testing: Evaluate the stability of drugs under different conditions through accelerated and long-term stability tests.
• Immunogenicity assessment: Predicting and evaluating the immunogenicity of drugs to help reduce the risk of potential immune reactions.

Protheragen-ING Lab's method development services
