[ USAGE ]

Reconstitute in ddH2O to a concentration of 0.1-0.4 mg/mL. Do not vortex

[ STORAGE AND STABILITY ] 

Storage: Avoid repeated freeze/thaw cycles. 

               Store at 2-8ºC for one month. 

               Aliquot and store at -80ºC for 12 months. 

Stability Test:  The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
