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: The PKLR protein solution (1mg/1ml) contains 20mM Tris-HCl buffer (pH8.0), 1mM DTT 0.2M NaCl and 10% glycerol. Greater than 90.0% as determined by SDS-PAGE.
Biological Activity: Specific activity: > 0.1 unit/mg. One unit will form 1.0 umol of phospho(enol)pyruvate to pyruvate per minute at pH 7.5 at 37C.
