Synonyms Mammotropin, Luterotropic hormone, Lutetropin, PRL.
Description Prolactin Rat Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 198 amino acids and having a molecular mass of 22.6 kDa. The Prolactin is purified by proprietary chromatographic techniques.
Uniprot Accesion Number P01237
Amino Acid SequenceThe sequence of the first five N-terminal amino acids was determined and was found to be Met-Leu-Pro-Val-Cys.
Source Escherichia Coli.
Physical Appearance and 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.
Formulation and Purity The protein was lyophilized from a concentrated (1mg/ml) solution with 10mM sodium Phosphate buffer pH=8 and 50mM Nacl. Greater than 95.0% as determined by
Application
Solubility It is recommended to reconstitute the lyophilized Prolactin in sterile 18MO-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The ED50 as determined by the dose-dependant stimulation of the proliferation of rat lymphoma, Nb2-11 was found to be < 0.065 ng/ml corresponding to a specific activity of 15,400,000 Units/mg.
Shipping Format and Condition Lyophilized powder at room temperature.
