Endotoxin : |
Less than 1 EU/mg of rHuSOD, His as determined by LAL method. |
Purity : |
>95% by SDS-PAGE and HPLC analyses. |
Storage : |
This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 or -70 centigrade. Avoid repeated freeze/thaw cycles. |
Storage Buffer : |
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH 7.4. |
Reconstitution : |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20 centigrade. Further dilutions should be made in appropriate buffered solutions. |
