PRL R Protein
Recombinant of PRL R protein
Product Specifications
Product Name Alternative
PRL-R, Prolactin receptor, Lactogen receptor, Prlr.
Source
Escherichia Coli
Purity
Greater than 97.0% as determined by: (a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.
Bioactivity
Activity is determined by the dose-dependant inhibition of Prolactin-stimuled proliferation of Nb2 cells and by high affinity binding of oPLR and other lactogenic hormones.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility
It is recommended to reconstitute the lyophilized PRL-R in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Storage Conditions
Stability: Lyophilized PRL-R although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Prolactin Receptor 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
Notes
For research use only.
Applications Notes
Protein content: Protein quantitation was carried out by two independent methods 1. UV spectroscopy at 280 nm using the absorbency value of 2.48 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics) .2. Analysis by RP-HPLC, using a standard solution of PRLr-ECD as a Reference Standard
Preservative
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
AA Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Gly-Lys-Pro-Glu-Ile
