Comprehensive Stability Studies

Our professional peptide stability testing services provide critical data on peptide degradation kinetics, shelf life, and optimal storage conditions. We conduct both accelerated and long-term stability studies following ICH guidelines to support research applications and regulatory submissions.

Accelerated Stability Testing

Elevated temperature and humidity studies to predict peptide degradation and estimate shelf life in shortened timeframes (3-6 months).

Long-Term Stability Studies

Real-time stability monitoring under recommended storage conditions to establish definitive shelf life (6-36 months).

Stress Testing

Exposure to extreme conditions (temperature, pH, light, oxidation) to identify degradation pathways and formulation weaknesses.

Freeze-Thaw Studies

Multiple freeze-thaw cycle testing to determine peptide stability during storage, shipping, and handling.

What We Measure

Purity Changes

HPLC analysis at each timepoint to track peptide purity and formation of degradation products

Chemical Degradation

Mass spectrometry to identify oxidation, deamidation, hydrolysis, and other chemical modifications

Physical Changes

Visual inspection, pH measurement, and analysis of aggregation, precipitation, or color changes

Concentration Stability

Quantification to assess concentration changes due to degradation or adsorption to container surfaces
