Biological potency is determined by an in vitro clot lysis assay and is expressed in International Units (IU).
The reconstituted preparation results in a colorless to pale yellow transparent solution containing Activase 1 mg/mL at approximately pH 7.3. The osmolality of this solution is approximately 215 mOsm/kg.
