Catalog #: CYT-311
Description:
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.
Synonyms:
Mammotropin, Luteotropic hormone, Luteotropin, PRL.
Source:
Escherichia Coli.
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.
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 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
Ovine Prolactin was lyophilized from a concentrated (1mg/ml) solution with 0.02%-0.03% NaHCO3.
Stability:
Lyophilized Ovine Prolactin Antagonist although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution Ovine Prolactin Antagonist should be stored at 4 °C between 2-7 days and for future use below -18 °C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
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.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage:
Denovo Biotechnology's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
