N/A

The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Pro-Val-Cys-Pro.

Ovine Prolactin Antagonist mutant form is devoid of agonistic activity and capable of inhibiting biological activity of oPRL or other lactogenic hormones as evidenced by proliferation assay of Nb2 or other cells. The truncated form is more potent inhibitor.

Ovine Prolactin was lyophilized from a concentrated (1mg/ml) solution with 0.02%-0.03% NaHCO₃.

Sterile Filtered White lyophilized (freeze-dried) powder.

Greater than 99.0% as determined by Gel Filtration & SDS-PAGE.

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

Escherichia Coli.

Lyophilized Ovine Prolactin Antagonist although stable at room temperature for 3 weeks, should be stored desiccated below -18^oC. Upon reconstitution Ovine Prolactin Antagonist 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.
