Storage & Handling
−| Storage | Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months. |
|---|---|
| Form/Appearance | Lyophilized |
| Buffer/Preservatives | 0.2 μm filtered solution of 20mM Sodium Citrate,0.02%Tween 80,4%Mannitol,pH 3.0. |
| Reconstitution | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
