On your website, it says potency of B1521 is ≥ 550 μg/mg. What does this mean? Does it mean that the purity of this protein is 55%?
550 µg/mg refers to the potency of the product. It means 550 μg of activity per mg of the dried material. This does not correspond to the purity of the product. We offer approximately 90% pure Apramycin Sulfate (purity by calculation: 100% - % total impurities).
