 [ USAGE ]

Reconstitute in 100mM NaHCO3, 500mM NaCl (pH8.3) to a concentration of0.1-1.0 mg/mL. Do not vortex.

[ STORAGE AND STABILITY ]

Storage: Avoid repeated freeze/thaw cycles. Store at 2-8

oC for one month. Aliquot and store at -80

oC for 12 months. 

Stability Test: The thermal stability is described by the loss rate. The loss ratewas determined by accelerated thermal degradation test, that is, incubate theprotein at 37oC for 48h, and no obvious degradation and precipitation wereobserved.The loss rate is less than 5% within the expiration date under

appropriate storage condition.
