Density gradient centrifugation was used for identification of particulates in vaccines formulated with aluminum phosphate (AlPO(4)) adjuvant. Protein-derived particulates are sporadically seen in protein pre-filled formulations where siliconized syringes are employed. These particulates are difficult to distinguish from the AlPO(4)
