1. Positive control for Western blot.
2. Antibody production.
3. Protein assay.

The protein was lyophilized from a concentrated (1mg/ml) solution with 1X PBS, 0.1% SDS and 1mM DTT.

Sterile Filtered White lyophilized (freeze-dried) powder.

Greater than 80.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

It is recommended to reconstitute the lyophilized Osteoprotegerin in sterile 18MΩ-cm H₂O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Escherichia Coli.

Lyophilized Osteoprotegerin although stable at room temperature for 3 weeks, should be stored desiccated below -18^oC. Upon reconstitution OCIF should be stored at 4^oC between 2-7 days and for future use below -18^oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
