EREG Human

Epiregulin Human Recombinant

Epiregulin Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 50 amino acids and having a molecular mass of 6 kDa.
Epiregulin is purified by proprietary chromatographic techniques.

Accession

O14944

Amino acid sequence

MVAQVSITKC SSDMNGYCLH GQCIYLVDMS QNYCRCEVGY TGVRCEHFFL.

Biological Activity

The ED50 was determined by the dose-dependent stimulation of the proliferation of murine Balb/3T3 cells is < 2.0 ng/ml, corresponding to a specific activity of > 500,000 units/mg.

Formulation

Epiregulin was lyophilized from 0.5mg/ml solution ciontaing 20mM PBS buffer pH-7.4 containing 130mM sodium chloride.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

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

Solubility

It is recommended to reconstitute the lyophilized Epiregulin in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

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

Synonyms

EREG, Epiregulin, ER.
