Peptide Stability Testing
The stability of peptides is a critical factor in pharmaceutical development and quality control. Peptides are complex biomolecules that require rigorous testing to ensure their integrity, efficacy, and safety throughout the entire shelf life. This service involves a series of tests designed to assess how peptide formulations behave over time under various environmental conditions.
Peptides can degrade through several mechanisms such as hydrolysis, oxidative damage, and enzymatic cleavage. These degradations can lead to a loss in biological activity or even the formation of potentially harmful by-products. Therefore, understanding these stability parameters is essential for ensuring that peptides remain safe and effective over their shelf life.
Our peptide stability testing service follows international standards such as ICH Q5C, which provides guidance on chemical stability information to support drug registration. The process includes accelerated aging studies, long-term stability studies, and intermediate stability tests. Each of these tests is designed to simulate real-world conditions that a product might encounter during storage or use.
In an accelerated aging study, samples are exposed to extreme conditions such as high temperature and humidity for extended periods. This helps predict how the peptide will degrade under more severe environmental stressors than typical commercial storage conditions. The results from this test provide valuable insights into potential stability issues that may arise during transit or long-term storage.
The long-term stability study, on the other hand, aims to assess the shelf life of a peptide product by storing it under normal or slightly elevated temperature and humidity conditions over an extended period. This allows us to determine if there are any significant changes in potency or quality that could impact patient safety.
For some peptides, especially those with lower stability profiles, we also conduct intermediate stability tests. These tests provide additional data points between the results of an accelerated aging study and a long-term stability study. Intermediate studies help refine our understanding of the degradation processes involved and allow us to make more precise predictions about shelf life.
