P01308

27 units/mg.
Insulin has been evaluated in cell culture (Human Foreskin Fibroblasts).
The effective concentration range for use in defined media is 1-5ug/ml. However, the optimum concentration range for a particular application must be determined by the investigator.

The protein was lyophilized from 50mM Sodium Chloride solution.

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 PBS pH-7.5.

Saccharomyces cerevisiae.

Lyophilized Insulin should be stored at 4^oC. Upon reconstitution Insulin should be stored at -20^oC to -80^oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
