The protein was lyophilized from a concentrated solution (1mg/ml) containing PBS (pH 7.4) and 0.05% NaN3.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized B2M in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized B2M although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution B2M should be stored at 4oC between 2-7 days and for future use below
-18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Beta-2-microglobulin, B2M.
