Long R3 IGF-1 has been studied and used for many years as a growth-supporting supplement in serum-free and reduced-serum media, including in industrial mammalian expression systems, where the practical questions are how much of it survives in medium over a culture cycle, whether it can substitute for insulin at far lower molar input, and how it interacts with the binding proteins that cells themselves secrete into conditioned medium
When it is exposed to air during the blending and "ultrasonicating" process, it can begin to lose its potency
