My BioMag is about to expire, is it still any good?
FAQ ID -268

Since the BioMag base particle is simply an Iron Oxide particle with a coating, the particle itself is very stable. The primary aspect of a BioMag particle that can degrade over time is the antibodies/proteins themselves. The antibody can loose its effectiveness over long periods of time or the protein may degrade. Although the expiration dates on BioMag are set at 2 years, if stored properly at 4°C and kept tightly sealed to prevent bacterial contamination, BioMag will likely perform properly even after the expiry date has passed. But please understand that we only can guarantee for the performance of the BioMag particle until the expiry date.
