The volume of this product is lot specific and dependent upon the protein content and enzymatic activity. Volume may be determined using the specific activity value and mg protein/mL value reported in the Certificate of Analysis. For example, if the end-user has 500KU pack size and the specific activity is reported as 700 units/mg, while the concentration is 20.1 mg/ml. The volume would equate to roughly 35.52 mL.
