Physical Appearance and Stability: Store at 4C if entire vial will be used within 2-4 weeks. Store, frozen at -20C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
Formulation and Purity: ADA protein 0.5mg/ml is supplied in 20mM Tris-HCL, pH-8, 1mM DTT and 20% Glycerol. Greater than 85.0% as determined by SDS-PAGE.
Biological Activity: Specific activity: approximately > 25 units/mg. Enzymatic activity was confirmed by measuring the amount of enzyme that deaminates 1.0 umol of adenosine to inosine per minute at pH 7.5 at 25C.
