Usage
TSZGENE's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.

Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Gln-Ser-Pro-Pro-Glu.

Description
Prolactin Receptor Ovine Extra Celleular Domain Recombinant ?produced in E.Coli is a non-glycosylated, Polypeptide chain containing 213 amino acids and having a molecular mass of 24.4 kDa.
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
Protein quantitation was carried out by two independent methodsUV spectroscopy at 280 nm using the absorbency value of 2.78 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, PRLR, OPR, PRLrI.
