Prolactin Ovine Antagonist

Prolactin Ovine Antagonsit Recombinant

Prolactin Ovine Antagonist Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 199 amino acids and having a molecular mass of 23kDa.
Ovine Prolactin Antagonist is purified by proprietary chromatographic techniques.

Accession

N/A

Amino acid sequence

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

Biological Activity

Ovine Prolactin Antagonist is devoid of agonistic activity and capable of inhibiting biological activity of Ovine Prolactin or other lactogenic hormones as evidenced by proliferation assay of Nb2 or other cells.

Formulation

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

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 99.0% as determined by SDS-PAGE.

Solubility

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.

Source

Escherichia Coli.

Stability

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

Synonyms

Mammotropin, Luteotropic hormone, Luteotropin, PRL.
