CAT No.BT-CYT-268

Prolactin Rabbit Soluble Receptor Recombinant, PRL R Rabbit, 50ug

---

Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Gly-Lys-Pro-Phe-Ile.

Biological Activity
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.

Description
Prolactin Receptor Rabbit Extra Celleular Domain Recombinant ?produced in E.Coli is a non-glycosylated, Polypeptide chain containing 207 amino acids and having a molecular mass of 23972 Dalton.
The Prolactin Receptor is purified by proprietary chromatographic techniques.

The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Protein content
UV spectroscopy at 280 nm using the absorbency value of 2.63 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).

Purity
Greater than 97.0% as determined by:
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized PRL-R in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized PRL-R although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution Prolactin Receptor should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Synonyms
PRL-R.
