Human PRL R Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant PRL R based upon sequence from Human
Host: QP10846 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of PRL R was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized PRLR in sterile 18M-cm H2O not less than 100µg/ml and not more than 1 mg/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: Activity is determined by the dose-dependant inhibition of Prolactin stimuled proliferation of Nb2 cells and by high affinity binding of ovine Prolactin and other lactogenic hormones in 1:1 molar ratio.

Purity: Greater than 97.0% as determined by:(a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE. (c) Gel filtration at pH 8 under non denaturative conditions.
Concentration of Human PRL R Protein: UV spectroscopy at 280 nm using the absorbency value of 2.63 as the extinction coefficient for a 0.1% (1 mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
Endotoxin Levels: < 1.0 EU per ug protein as determined by the LAL method.
Buffer: The Prolactin Receptor was lyophilized from a concentrated (0.4 mg/ml) solution with 0.0045mM NaHCO3.
Storage Conditions: Lyophilized PRL-R although stable at room temperature for 1-2 weeks, should be stored desiccated below -18°C or preferably even at -80°C to prevent dimer formation. Upon reconstitution PRL-R should be stored sterile at 4°C between 2-7 days and for future use below -18°C. For long term storage at 4°C it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles as they cause oligomerization of the protein.
Physical Appearance: Sterile filtered white lyophilized powder.
