Abstract

Methods of treating a dialysis component by providing a dialysis component and contacting the dialysis component with an enzyme are provided. The enzyme breaks down microbial contaminants in the dialysis component. The enzyme may be separated from the dialysis component to provide a purified dialysis component. The purified dialysis component may be substantially free of microbial contaminants that cause a cytokine response in humans.
