Humidity is the Enemy
Nitrocellulose membranes are highly hygroscopic. Excess moisture can alter the pore structure and degrade antibody activity over time. Proper packaging with high-grade silica desiccants is non-negotiable.
Accelerated Aging Protocols
To validate a 24-month shelf life, we employ Arrhenius equation-based accelerated aging tests (e.g., storing strips at 55°C for weeks). Due Bio Universal Strips are rigorous tested to ensure signal stability remains >95% even after thermal stress.
