Description
| Product Name: | Human Prolactin Recombinant Protein |
| Product Code: | RPPB0869 |
| Size: | 50µg |
| Species: | Human |
| Target: | Prolactin |
| Synonyms: | Mammotropin, Luteotropic hormone, Luteotropin, PRL. |
| Source: | Escherichia Coli |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | The protein was lyophilized from a concentrated (1mg/ml) solution with 10mM sodium Phosphate buffer pH=8 and 50mM Nacl. |
| Solubility: | It is recommended to reconstitute the lyophilized Prolactin in sterile 18M?-cm H2O not less than 100�g/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. |
| Purity: | Greater than 95.0% as determined by:(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE. |
| 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 |
| 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. |
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.
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.
| UniProt Protein Function: | prolactin: Prolactin acts primarily on the mammary gland by promoting lactation. Belongs to the somatotropin/prolactin family. |
| UniProt Protein Details: | Protein type:Secreted, signal peptide; Secreted; Cytokine; Motility/polarity/chemotaxis Chromosomal Location of Human Ortholog: 6p22.3 Cellular Component: extracellular region Molecular Function:protein binding; prolactin receptor binding; hormone activity Biological Process: lactation; cell proliferation; cell surface receptor linked signal transduction; regulation of multicellular organism growth; positive regulation of JAK-STAT cascade; female pregnancy |
| NCBI Summary: | This gene encodes the anterior pituitary hormone prolactin. This secreted hormone is a growth regulator for many tissues, including cells of the immune system. It may also play a role in cell survival by suppressing apoptosis, and it is essential for lactation. Alternative splicing results in multiple transcript variants that encode the same protein.
