We are a "Class 1 Exempt" IVD Medical Device company both ISO 9001 and 21 CFR Part 820 certified. Do our products need "Real Time Stability" or "Accelerated Stability" should be good enough? Also, Do each and every product that's design need stability or just a product family? Because most of our products are just Antibodies, Reagents and Chromogen families. Thank you.
