The Biological Activity was determined to be 28 units/mg.
The protein was lyophilized from a concentrated (1mg/ml) solution with no additives.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Insulin in sterile 0.005N HCl not more than 1 mg/ml.
Lyophilized Insulin although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Insulin 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.
