< 1.0 EU per μg protein as determined by the LAL method.

Freeze-dried powder

Lyophilized from a 0.22 um filteredsolution of PBS, pH 7.4. or Supplied as a0.22 um filtered solution in PBS, pH7.4

Centrifuge the vial before opening.Reconstitute to a concentration of0.1-0.5 mg/mL in sterile distilled water.Avoid vortex or vigorously pipetting theprotein. For long term storage, it isrecommended to add a carrier protein orstablizer (e.g. 0.1% BSA, 5% HSA, 10%FBS or 5% Trehalose), and aliquot thereconstituted protein solution tominimize free-thaw cycles.

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℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
