Purification strategies vary according to the product and the intended use and include immunoaffinity purification of individual relevant proteins, conventional chromatographic separations, ultracentrifugation, and proprietary extraction methodologies. In all cases, antigen function, stability, and reproducibility are given the critical attention necessary to ensure that our antigens are of the highest quality available.
Each batch of antigen, after extraction, purification, and titer adjustment, is aliquoted to two-vial sizes (1.0 and 25 milliliters) before freezing and final quality control testing. In this way, a one-milliliter sample of a particular lot truly represents the larger size aliquot.
