Sheep Prolactin Antagonist (Mutant) Protein

• Catalog Number: orb427878
• Category: Proteins
• Description: Recombinant of sheep Prolactin Antagonist (Mutant) protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: Ovine Prolactin was lyophilized from a concentrated (1mg/ml) solution with 0.02%-0.03% NaHCO3.
• Purity: Greater than 99.0% as determined by Gel Filtration & SDS-PAGE.
• Protein Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Pro-Val-Cys-Pro
• Application notes: Cytokines And Growth Factors
• Source: Escherichia Coli
• Biological Activity: 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.
• Solubility (25°C): It is recommended to reconstitute the lyophilized Ovine Prolactin Antagonist in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Storage: 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
• Alternative names: Mammotropin, Luteotropic hormone, Luteotropin, PRL
• Note: For research use only
• Expiration Date: 6 months from date of receipt.
