HPLC Analysis Shows Vitamin D Supplement Potency Varies
The amount of vitamin D in supplements can range from 9% to 146% of the stated dose, according to a research letter published in the JAMA Internal Medicine.
Essential to the development of biotherapeutics is ability to quickly and accurately assess product quality—including factors such as sequence integrity, glycan heterogeneity, and purity—at each step. Thermo Scientific workflows for intact-protein analysis enable these assessments early in the development process without the effort of complete characterization and allowing you to make better, faster decisions about how to proceed with your biotherapeutic development.
