Sample solution is provided at 25 µL, 10mM.
Prolactin Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 200 amino acids and having a molecular mass of 23007 Dalton. The Prolactin is purified by proprietary chromatographic techniques.
Purity | Greater than 95.0% as determined by:(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE. | Source | Escherichia Coli. |
Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
Synonyms | Mammotropin; Luteotropic hormone; Luteotropin; PRL. | ||
Amino Acid Sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Met-Leu-Pro-Ile-Cys. | ||
Solubility | It is recommended to reconstitute the lyophilized Prolactin in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
Stability | Lyophilized Prolactin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution Prolactin 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. | ||
Biological Activity | The ED50 as determined by the dose-dependant stimulation of the proliferation of rat lymphoma, Nb2-11 was found to be < 0.065ng/ml corresponding to a Specific Activity of 15,385,000IU/mg. | ||
Formulation | The protein was lyophilized from a concentrated (1mg/ml) solution with 10mM sodium Phosphate buffer pH=8 and 50mM Nacl. |
Prolactin is a neuroendocrine hormone synthesized primarily by the pituitary gland but also a variety of other cell types including the placenta, brain and uterus. Its primary function is to promote and maintain lactation but has also been shown to have a role in breast cancer development, regulation of reproductive function and immunoregulation.
